Do we make crate no_std compatible possibly

I noted that #530. It has been inactive for a year. I have the same issue with no_std support.

All the "OS dependent" things that gleam uses are type definitions, it's not necessary to depend on the std crate.

there's other crates like gl33, gl46, or you could probably run phosphorus to spit out the bindings of another api level, and those crates run in no_std
