Tyler Wilding d1ece445d4 Dependency graph work - Part 1 - Preliminary work (#3505)
Relates to #1353 

This adds no new functionality or overhead to the compiler, yet. This is
the preliminary work that has:
- added code to the compiler in several spots to flag when something is
used without being properly required/imported/whatever (disabled by
default)
- that was used to generate project wide file dependencies (some
circulars were manually fixed)
- then that graph underwent a transitive reduction and the result was
written to all `jak1` source files.

The next step will be making this actually produce and use a dependency
graph. Some of the reasons why I'm working on this:
- eliminates more `game.gp` boilerplate. This includes the `.gd` files
to some extent (`*-ag` files and `tpage` files will still need to be
handled) this is the point of the new `bundles` form. This should make
it even easier to add a new file into the source tree.
- a build order that is actually informed from something real and
compiler warnings that tell you when you are using something that won't
be available at build time.
- narrows the search space for doing LSP actions -- like searching for
references. Since it would be way too much work to store in the compiler
every location where every symbol/function/etc is used, I have to do
ad-hoc searches. By having a dependency graph i can significantly reduce
that search space.
- opens the doors for common shared code with a legitimate pattern.
Right now jak 2 shares code from the jak 1 folder. This is basically a
hack -- but by having an explicit require syntax, it would be possible
to reference arbitrary file paths, such as a `common` folder.

Some stats:
- Jak 1 has about 2500 edges between files, including transitives
- With transitives reduced at the source code level, each file seems to
have a modest amount of explicit requirements.

Known issues:
- Tracking the location for where `defmacro`s and virtual state
definitions were defined (and therefore the file) is still problematic.
Because those forms are in a macro environment, the reader does not
track them. I'm wondering if a workaround could be to search the
reader's text_db by not just the `goos::Object` but by the text
position. But for the purposes of finishing this work, I just statically
analyzed and searched the code with throwaway python code.

ManDude cd68cb671e deftype and defmethod syntax major changes (#3094)
Major change to how `deftype` shows up in our code:
- the decompiler will no longer emit the `offset-assert`,
`method-count-assert`, `size-assert` and `flag-assert` parameters. There
are extremely few cases where having this in the decompiled code is
helpful, as the types there come from `all-types` which already has
those parameters. This also doesn't break type consistency because:
  - the asserts aren't compared.
- the first step of the test uses `all-types`, which has the asserts,
which will throw an error if they're bad.
- the decompiler won't emit the `heap-base` parameter unless necessary
now.
- the decompiler will try its hardest to turn a fixed-offset field into
an `overlay-at` field. It falls back to the old offset if all else
fails.
- `overlay-at` now supports field "dereferencing" to specify the offset
that's within a field that's a structure, e.g.:
```lisp
(deftype foobar (structure)
  ((vec    vector  :inline)
   (flags  int32   :overlay-at (-> vec w))
   )
  )
```
in this structure, the offset of `flags` will be 12 because that is the
final offset of `vec`'s `w` field within this structure.
- **removed ID from all method declarations.** IDs are only ever
automatically assigned now. Fixes #3068.
- added an `:overlay` parameter to method declarations, in order to
declare a new method that goes on top of a previously-defined method.
Syntax is `:overlay <method-name>`. Please do not ever use this.
- added `state-methods` list parameter. This lets you quickly specify a
list of states to be put in the method table. Same syntax as the
`states` list parameter. The decompiler will try to put as many states
in this as it can without messing with the method ID order.

Also changes `defmethod` to make the first type definition (before the
arguments) optional. The type can now be inferred from the first
argument. Fixes #3093.

Hat Kid fc43870d85 decompiler: obj -> this, set-time! and time-elapsed? macros (#3026)
This renames the method object in `defmethod`s to `this` and adds
detection for the `set-time!` and `time-elapsed?` macros.

Definitely my biggest PR yet...

ManDude ff924f6b00 improve decomp of state handlers and art groups (#3014)
- state handlers that are not inlined lambdas have smarter type
checking, getting rid of 99.9% of the casts emitted (they were not
useful)
- art groups were not being properly linked to their "master" groups.
- `max` in `ja` in Jak 2 was not being detected.

Another huge PR...

ManDude fe491c2b5e [opengoal] make none a child of object (#3001)
Previously, `object` and `none` were both top-level types. This made
decompilation rather messy as they have no LCA and resulted in a lot of
variables coming out as type `none` which is very very wrong and
additionally there were plenty of casts to `object`. This changes it so
`none` becomes a child of `object` (it is still represented by
`NullType` which remains unusable in compilation).

This change makes `object` the sole top-level type, and the type that
can represent *any* GOAL object. I believe this matches the original
GOAL built-in type structure. A function that has a return type of
`object` can now return an integer or a `none` at the same time.
However, keep in mind that the return value of `(none)` is still
undefined, just as before. This also makes a cast to `object`
meaningless in 90% of the situations it showed up in (as every single
thing is already an `object`) and the decompiler will no longer emit
them. Casts to `none` are also reduced. Yay!

Additionally, state handlers also don't get the final `(none)` printed
out anymore. The return type of a state handler is completely
meaningless outside the event handler (which is return type `object`
anyway) so there are no limitations on what the last form needs to be. I
did this instead of making them return `object` to trick the decompiler
into not trying to output a variable to be used as a return value
(internally, in the decompiler they still have return type `none`, but
they have `object` elsewhere).

Fixes #1703 
Fixes #830 
Fixes #928

Tyler Wilding 66e48195cb jak1: Consolidate art-elts into a single file as is done in jak 2 (#2887)
Fixes #2167

Reduces test flakiness if ran on multiple threads and gets rid of a few
hundred files from the source tree

I believe this also makes #1434 irrelevant and it can be closed.

Hat Kid f4085a4362 jak1: clean up all dummy methods (#2457)
Cleans up every `dummy-*` and `TODO-RENAME-*` method up with either
proper names or by renaming them to `[type-name]-method-[method-id]`
similar to Jak 2's `all-types`.

Also fixes the bad format string in `collide-cache` and adds the event
handler hack to Jak 1.

The game boots and runs fine, but I might have missed a PAL patch or
other manual patches here and there, please double-check if possible.
