  [LLDB] Add support for Arm64/Linux dynamic register sets

This is patch adds support for adding dynamic register sets for
AArch64 dynamic features in LLDB. AArch64 has optional features like
SVE, Pointer Authentication and MTE which means LLDB needs to decide
at run time which registers it needs to pull in for the current
executable based on underlying support for a certain feature.

This patch makes necessary adjustments to make way for dynamic
register infos and dynamic register sets.

  -----------
  [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.

This patch adds a test case to test AArch64 dynamic register sets.
This tests for the availability of certain register sets and query
their registers accordingly.
