cosmopolitan: Update compiler and update platform_internal.h (#3079)

Browse Source 
This fixes the cosmopolitan platform.
- Switch `build_cosmocc.sh` and platform documentation to
  explicitly use the x86_64 cosmocc compiler as multi-arch
  cosmocc won't work here. Older version `cosmocc` just did
  a x86_64 build.
- Add missing items from `platform_internal.h` to fix build.
