  [clang-tidy] Fix crash in readability-identifier-naming (#220221)

This PR contains the fix for the `readability-identifier-naming` crash.
The crash happens because the checker calls `hasMemberName` on a base
class without checking if that base class actually has a definition
first (like when it's just forward-declared). I added a
`RD->hasDefinition()` guard to fix it.

Fixes #213948
