[PATCH v3][COMMITTED] aarch64: Support 2024 Debug Architecture system registers.

[Srinath Parvathaneni]

Changes from v2->v3:
* Removed the default values or the sys_reg parameter name from the
  tests.

------------------
This patch adds support for following system registers and the spec
can be found here[1].
1. PMBSR_EL12, PMBSR_EL2, PMBSR_EL3, PMBMAR_EL1 depends on FEAT_SPE
   and Armv9.5-A architecture and these are enabled by passing
   -march=armv9.5-a+profile.
2. TRBSR_EL12, TRBSR_EL2, and TRBSR_EL3 depends Armv9.5-A architecture
   and these are enabled by passing -march=armv9.5-a.
3. HFGITR2_EL2 depends on Armv8.8-A architecture and enabled by passing
   -march=armv8.8-a.

Regression tested for aarch64-none-elf target and found no regressions.

Ok for binutils-master?

Regards,
Srinath.
