perf clang-format: Prioritize Python.h and expand other categories

This commit updates the .clang-format rules for the perf tools.
It prioritizes Python.h sorting and expands the regex lists for C
standard library and OS specific headers.

- Prioritize Python.h by sorting it first (Priority -1), ensuring it
  is sorted before even the main header (Priority 0).
- Keep other header priorities (1 and 2) to maintain their relative
  order.
- Sanity check and complete "C Standard Library Headers" up to C23
  (added stdbit.h, stdckdint.h).
- Sanity check and complete "OS/System-Specific Headers" based on
  actual usage in tools/perf (added asm-generic, uapi, and various
  flat POSIX/system headers).
