[libc++] Remove the allocator<const T> extension (#96319) ...

This effort has quite a history:
- This was first attempted in 2022 via bed3240bf7d1, which broke
std::shared_ptr<T const> and caused the change to be reverted in
9138666f5464.
- We then re-attempted landing the change in 276ca87382b8 after fixing
std::shared_ptr, but reports were made that this broke code en masse
within Google. This led to the patch being reverted again in
a54d028895c9 with the goal to land this again with a migration path for
vendors.

This patch re-lands the removal while providing a migration path for
vendors by providing the `_LIBCPP_ENABLE_REMOVED_ALLOCATOR_CONST` macro.
This macro will be honored for the LLVM 19 release and will be removed
after that, at which point allocator<const T> will be removed
unconditionally.

Fixes #73665
