HanifKoh d1afb1fed6 Use a System clang-tidy When Available and Make --fix Converge in One Pass (#16199)
* Use a System clang-tidy When Available and Make --fix Converge in One Pass

scripts/run_clang_tidy.sh only looked at CLANG_TIDY and the venv it creates,
so a clang-tidy already on the system was never used. It is now the first
choice: the pinned version outright, another version after a prompt that
says results may differ slightly from CI, which -y and an existing pinned
venv skip.

Two problems in clang_tidy_diff.py made --fix need several runs and still
leave the plain check failing:

- A deleted #include orphans uses on unchanged lines. The plain check runs
  such a file whole and reports them, but --fix kept the line filter to the
  changed lines, so they were never fixed. Fix mode now runs the file whole
  first and then fixes exactly the changed lines plus the lines that run
  found wanting, so unrelated lines are still never rewritten.

- clang-tidy exits non-zero for the findings it just fixed, so every fixed
  file was reported as failed and the user ran --fix again to see what was
  left. A file --fix changed is now checked again and the fixed files are
  listed separately from what --fix could not add.

CI runs the script without --fix and is unchanged.

* Keep the a/ b/ Diff Prefixes Whatever the User's Git Config Says

parse_diff recognises a changed file by its +++ b/ header. With
diff.noprefix or diff.mnemonicPrefix set, git prints +++ src/x.cpp or
+++ w/src/x.cpp instead, every file was dropped, and the local check
reported no changed C++ lines. The diff is now asked for the a/ and b/
prefixes outright, which overrides both settings.

* Warn When No Remote Points at OrcaSlicer/OrcaSlicer

Without one, run_clang_tidy.sh compares against origin/main. When origin
is a fork whose main already holds the commits, the check finds nothing
and says so, without hinting at why. The script now names the base it
fell back to and how to point it at the upstream repository.
