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.

water111 0e31a9c407 [decompiler] Handle find-parent-method (#3018)
This change adds a few new features:
- Decompiler automatically knows the type of `find-parent-method` use in
jak 1 and jak2 when used in a method or virtual state handler.
- Decompiler inserts a call to `call-parent-method` or
`find-parent-state`
- Removed most casts related to these functions

There are still a few minor issues around this:
- There are still some casts needed when using `post` methods, as `post`
is just a `function`, and needs a cast to `(function none)` or similar.
It didn't seem easy to change the type of `post`, so I'm not going to
worry about it for this PR. It only shows up in like 3 places in jak 2.
(and 0 in jak 1)
- If "call the handler if it's not #f" logic should probably be another
macro.

Fixes #805

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 7170db51ea fix bad defpartgroup decomp and improve entity debug display a bit (#2423)
- Makes very nasty bugs fixed in #2402 print onscreen when detected
instead of to the console.

- Fixes `valid?` decomp
- Moves `entity-debug.gc` to the end of `COMMON.CGO` so we can check for
keys in a few more commonly-used actor types.
- Entity debug display (jak 2) now properly parses the `art-name` tag of
part spawners, which gets overwritten at runtime.
- Fixes #2422 . Decompiler was writing out part group rotation for the
scale part, so all of those part groups had a zero in one (or all) of
the axes. This "only" affected 38 groups, including all of the flame
pots in tomb, jetpack guard, wasp, onin tent seal of mar, dark eco pill
and a few other things.

Tyler Wilding 6181c6c997 decomp: output mips2c method/function declarations to the _disasm.gc file (#2054)
When working with mips2c recently, I noticed adding the
`defmethod-mips2c` or `def-mips2c` code was a manual step. This is a bit
tedious to have to go and do yourself, but more importantly you have to
manually go and find the right spot in the source file else you might be
declaring it too early or too late.

This will automatically output the declaration for methods, and a
half-finished comment for the functions. I wasn't able to fully output
the function one because it seems the signature info from `all-types`
doesn't make it all the way through -- but maybe I'm wrong or this is an
easy fix?
