This is a proof-of-concept how the [[clang::suppress(tags,...)]] attribute can
work with suppressing clang-tidy warnings.

The list of tags that can be used to suppress a specific warnings comes
from [1]. It is the group that the cppcoreguidelines check belongs to
("type"), the name of the check there ("type.1") and the clang-tidy
name ("cppcoreguidelines-pro-type-reinterpret-cast").

I envision to put this into all cppcoreguidelines checks. Alternatively,
this could go into clang-tidy core, to have this automatically for all
checks.

I'm looking forward to your comments!

Depends on: D24886
