[Editor/Vim] Update Vim syntax highlighting to match current version

[EndeyshentLabs]

I'm not entirely sure what else to add and would appreciate corrections. So far, I'm only sure about cfor, csize, and cusize.

As far as I understand, lambda, has, typeof, true, and false aren't used anywhere, but they seem to have implementations (though lambda doesn't work for me, but maybe I'm using it incorrectly).

Do they have to be capitalized? In lexer.cc, tests and examples they're all lowercase.

They used to have to be, but they no longer are; IIRC I left it because I meant to make everything case-insensitive, but never got around to it. bool, byte, etc is the proper "modern" Glint styling for built-in types

I haven't tested lambdas at all yet, I'll add some cases for it and make sure it's working. A lambda is basically supposed to act like name : before a function signature, and it just generates a unique name.

has is used to implement match; that is, match statements get rewritten into if else chain with has conditionals. It's often not used by the user but will be for certain cases.

typeof is used by semantic templates (the templates that sema uses to rewrite things), and it's effectively just decltype from cpp (gets the type of the expression without emitting it).

true and false are just constants, they are used to initialize variables, often (like the sdl example initializing running to true).

This PR looks good, and I'd merge it unless you want to add anything else

There is a list of keywords in lib/glint/lexer.cc right near the top if you want an exhaustive list

There are some test cases for lambdas now; they appear to be working afaik?
