Windows: Rework kernel32 apis

To facilitate ziglang#19037, this commit slims `std.windows.kernel32` to only
have the functions needed by the standard library. Since this will break
projects that relied on these, I offer two solutions:

- Make an argument as to why certain functions should be added back in.
  Note that they may just be wrappers around `ntdll` APIs, which would
  go against ziglang#19037.
  If necessary I'll add them back in *and* make wrappers in
  `std.windows` for it.
- Maintain your own list of APIs. This is the option taken by bun[1],
  where they wrap functions with tracing.
- Use `zigwin32`.

I've also added TODO comments that specify which functions can be
reimplemented using `ntdll` APIs in the future.

Other changes:
- Group functions into groups (I/O, process management etc.).
- Synchronize definitions against Microsoft documentation to use the
  proper parameter types/names.
- Break all functions with parameters over multiple lines.
