Runs run-clang-tidy. A bit meta. Maybe it will replace run-clang-tidy one day

# I hereby dedicate this script to fuck you meson.

# I cannot simply write my code to invoke a subprocess in a meson file because
|
|
# Meson corrupts backslashes in command line args to subprocesses.
|
|
# This is allegedly for "Windows support", but last time I checked Windows
|
|
# neither needs nor wants you to corrupt its command lines.
