  [analyzer] Add an ownership change visitor to StreamChecker (#94957)

This is very similar to https://reviews.llvm.org/D105553, in fact, I
barely made any changes from MallocChecker's ownership visitor to this
one.

The new visitor emits a diagnostic note for function where a change in
stream ownership was expected (for example, it had a fclose() call), but
the ownership remained unchanged. This is similar to messages regarding
ordinary values ("Returning without writing to x").
