[TBAA] Do not rewrite TBAA if exists, always null out `!tbaa.struct`
Retrieve `!tbaa` metadata via `!tbaa.struct` in `adjustForAccess`
unless it already exists, as struct-path aware `MDNodes` emitted
via `new-struct-path-tbaa` may be leveraged. As `!tbaa.struct`
carries memcpy padding semantics among struct fields and `!tbaa`
is already meant to aid to alias semantics, it should be possible
to zero out `!tbaa.struct` once the memcpy has been simplified.
`SROA/tbaa-struct.ll` test has gone out of scope, as `!tbaa` has
already replaced `!tbaa.struct` in SROA.
Fixes: https://github.com/llvm/llvm-project/issues/95661.
