bfabd5be - [libc++] Remove some private symbols from the ABI (#121497)

[libc++] Remove some private symbols from the ABI (#121497) These symbols are never referenced directly outside the dylib, so we can make them hidden instead. They are still in the dylib since can be referenced through the `memory_resource*`, but dynamic linkers don't have to do any work to deduplicate them.
