Lua Constant autocomplete support

[sturnclaw]

This PR improves our scan_enums script to dump the literal string constants into Lua type information files, providing an additional source of truth when trying to use those enums. It uses the LuaLSP ---@enum annotation to provide autocomplete for function parameters declared with an enum type (although it will currently also incorrectly suggest e.g. Constants.BodyType.1 if you don't type a " to filter the autocomplete results).

This also updates the enum_table file with the changes to the SystemBody enums merged as part of the Json system definition work.

Remind me, it's the lua-language-server that we're using, right?

Correct.

And to make use of this new power, one needs only use LSP in your IDE of choice + run the scan enum's python script?

All you need to do is use an LSP adapter to run lua-language-server and configure it to load meta files from data/meta - I've already run scan_enums.py and we check the meta files into the repository. Details of the configuration vary between IDEs - our "default" VScode workspace is pre-configured.
