Andrew Kelley 19eaf54bc9 update libc linux headers to v5.16-rc3
* Add missing Linux headers. Closes #9837
 * Update existing headers to latest Linux.
 * Consolidate headers that are the same for multiple Zig target CPU
   architectures. For example, Linux has only an x86 directory for both
   x86_64 and x86 CPU architectures. Now Zig only ships an x86 directory
   for Linux headers, and will emit the proper corresponding -isystem
   flags.
 * tools/update-linux-headers.zig is now available for upgrading to
   newer Linux headers, and the update process is now documented on the
   wiki.
