LOG: [Clang] [NFC] Refactor AST visitors in Sema and the static analyser to use DynamicRecursiveASTVisitor (#115144)
This pr refactors all recursive AST visitors in `Sema`, `Analyze`, and
`StaticAnalysis` to inherit from DRAV instead. This is over half of the
visitors that inherit from RAV directly.
See also #115132, #110040, #93462
