game: cleanup gk's CLI documentation (#2189)

An attempt to cleanup the last CLI interface we have left to cleanup. 
- `gk` args now follow the typical convention ie. `--proj-path` instead
of `-proj-path`.
- args that are passed through to the rest of the application / the
game's runtime use the typical convention of following a `--`
- I'm thinking some args shouldn't be handled at this level ie
(`-nodisplay`, `-vm`, `-novm` or `-jak2`) These could be better
documented as legitimate flags and passed in via a nice struct. They
don't seem to be used in `InitParams` but I'll triple check.

There's a temporary shim here so there is no coupled release with the
launcher (right now it executes `gk` with a few args). So I just change
the old args into the new format. After one release cycle, I can change
it in the launcher and delete it here.

I am unsure if this will break the bash shellscript usages -- not sure
which args were usually passed into `$@`
