Maintain backward compatibility by reintroducing the events that were
previously removed by commit 047979af3bf6 ("perf vendor events amd:
Update Zen 5 core events"). Also set the deprecated flag and update
the descriptions to point users to the correct alternative.

Closes: https://lore.kernel.org/all/CAP-5=fV_czvd-z4N7K+_SabxuOm9UUHRyBxNuchrtAgJL3OqOw@mail.gmail.com/
