Allow specifying type definition files from .luaurc

[Gargafield]

It's currently hard to use Luau analysis with custom libraries or environments.

I propose that the .luaurc file have a field that links to a file with custom type definitions.
These types would of course still use the old format.

This could be done with a global types file path. The file is a lua file with export type statements.

I'm using luau embedded in my app, this would be amazing. At the moment I need to define my custom types as global Any.

This would also enable doing more of the sort of thing https://github.com/lenscas/tealr is doing.

+1 on this issue, would perhaps re-using teal project's .d.tl declaration files be a possibility? As soon as declaration files exist I would love to integrate luau into https://github.com/makspll/bevy_mod_scripting

I believe the author of mlua is already looking into supporting luau. So, all that is needed on your end is a mlua version with that enabled, a luau version that supports something like .d.tl files and a tealr version that can generate whatever luau ends up with.

So.. as someone who only has control of 1 of the 3 things for that, I also do a +1 on this issue :)
