Add basic clang-tidy config
This has not yet had all the warnings Obliterated, but it is a start and is not *super* far away from being able to run the current configuration in CI, which will catch some limited number of mistakes. I tried the meson clang-tidy target and it seems to fail to find flags for several files, which seems broken. Unsure what is up with that, but we can use run-clang-tidy or other tooling instead. We have an extremely annoying situation with the lexer table, which means that the lexer probably must be moved to another directory with its own .clang-tidy file to disable the lints in it, *or* write scuffed code that prepends a disable comment to the top of the generated file. None of the comment-based lint disabling features work since yacc dumps a bunch of non compliant code at the top of the file before anything the user can control.
