  [SSAF][clang-reforge] Retrofit expressions after CppBoundedBuffers decl rewrites

PR #210457 introduces declaration rewriting.  When CppBoundedBuffers
rewrites a declaration or return type to a bounded_ptr/bounded_array,
some of the existing uses of that entity needs retrofit.

This commit creates expression rewrites for the following patterns:

- Append '.data()' to call arguments when necessary parameter is not
  transformed but argument is transformed.
- Append '.as_bounded<T>()' to call arguments when both parameter and
  argument are transformed but element types are not identical.
- Rewrite '&e[i]' to '(e + i)' and '&*e'/'&(*e)' to 'e', if 'e' is
  transformed.
- Rewrite '(T*)e', 'static_cast<T*>(e)', and 'reinterpret_cast<T*>(e)'
  to 'e.as_bounded<T>()', if 'e' is transformed.
