Without the "found declaration" it is later not possible to know where the operator declaration
was brought into the scope calling it.
The initial motivation for this fix came from #55095. However, this also has an influence on
`clang -ast-dump` which now prints a `UsingShadow` attribute for operators only visible through
`using` statements. Also, clangd now correctly references the `using` statement instead of the
operator directly.

Eliminate clutter by reorganizing the Lit test files for clang-tidy:
- Move checkers/<module>-* to checkers/<module>/*.
- Move module specific inputs from Inputs to <module>/Inputs. Remove
any module prefix from the file or subdirectory name as they are no
longer needed.
- Introduce a Lit substitution %clang_tidy_headers for the system
headers in checkers/Inputs/Headers and use this throughout. This
avoids referencing system headers through a relative path to the
parent directory and makes it clear that these fake system headers are
shared among all modules.
- Update add_new_check.py to follow the above conventions when creating
the boiler plate test files for a new check.
- Update Contributing.rst to describe per-module Inputs directory and
fix link to test source code.
