ClangTools: Query the tools for supported checks

...instead of hardcoding them for a particular version of
clang-tidy/clazy.

While at it, move also the tidy/clazy widgets to ClangTools as this
simplifies feeding data to them.

Reduce also the built-in configs to a single one using clang-tidy's and
clazy's default checks as they look very reasonable and saves us some
porting effort. Also, our previous built-in configs were just too
numerous.
