[RISCV] Add support for new unprivileged extensions defined in profiles spec (#77458)
This adds minimal support for 7 new unprivileged extensions that were defined as a part of the RISC-V Profiles specification here: https://github.com/riscv/riscv-profiles/blob/main/profiles.adoc#7-new-isa-extensions * Ziccif: Main memory supports instruction fetch with atomicity requirement * Ziccrse: Main memory supports forward progress on LR/SC sequences * Ziccamoa: Main memory supports all atomics in A * Zicclsm: Main memory supports misaligned loads/stores * Za64rs: Reservation set size of 64 bytes * Za128rs: Reservation set size of 128 bytes * Zic64b: Cache block size isf 64 bytes As stated in the specification, these extensions don't add any new features but describe existing features. So this patch only adds parsing and subtarget features.

Between versions 2.0 and 2.1 of the base I specification, a backwards incompatible change was made to remove selected instructions and CSRs from the base ISA. These instructions were grouped into a set of new extensions, but were no longer required by the base ISA. This change is partially described in "Preface to Document Version 20190608-Base-Ratified" from the specification document (the ``zicntr`` and ``zihpm`` bits are not mentioned). LLVM currently implements version 2.1 of the base specification. To maintain compatibility, instructions from these extensions are accepted without being in the ``-march`` string. LLVM also allows the explicit specification of the extensions in an ``-march`` string.

These extensions are defined as part of the `RISC-V Profiles specification <https://github.com/riscv/riscv-profiles/releases/tag/v1.0>`_. They do not introduce any new features themselves, but instead describe existing hardware features.
