[LLDB] Arm64/Linux Add MTE and Pointer Authentication registers

This patch adds two new dynamic register sets for AArch64 MTE and
Pointer Authentication features. These register sets are dynamic and
will only be available if underlying hardware support either of these
features. LLDB will pull in Aux vector information and create register
infos based on that information.

A follow up patch will add a test case to test these feature registers.
