aarch64: rename internals related to PAuth feature to use pauth in their naming for coherency

Hi,

Commits af1bd77 and 3f4ff08 introduced the Pointer Authentication feature with internal names that don't match the actual feature name pauth. The new feature PAuth_LR introduced in Armv9.5-A is an extension of the PAuth feature of Armv8.3-A. Using a different naming for it not based on the formerly "PAC" would create confusion.

Regression tested on aarch64-none-elf, and no regression found.

Ok for binutils-master? I don't have commit access so I need someone to commit on my behalf.

Regards,
Matthieu.
