[Arm][AArch64] Add support for v8.9-A/v9.4-A base extensions
This implements the base extensions that are part of the v8.9-A and
v9.4-A architecture versions, including:
* The Clear BHB Instruction (FEAT_CLRBHB)
* The Speculation Restriction Instruction (FEAT_SPECRES2)
* The SLC target for the PRFM instruction
* New system registers:
* ID_AA64PFR2_EL1
* ID_AA64MMFR3_EL1
* HFGITR2_EL2
* SCTLR2_EL3
More information on the new extensions can be found on:
