Updates are made to source and documentation.
This more accurately represents the currently supported platforms of
Android/Linux and Windows, without unexpectedly including other
unix-like operating systems.
Command to reproduce:
$ find . -type f -not -path '*/\.git/*' | xargs -I {} sed -i 's/cfg(unix)/cfg(any(target_os = "android", target_os = "linux"))/g' {}
$ cargo fmt
md files manually updated to fix line lengths.
Renaming `unix` modules to `linux` will be done in a later CL.
Test: ./tools/dev_container ./tools/presubmit
Bug: b/298269162
