  [Exegesis][RISCV] Add RISCV support for llvm-exegesis (#89047)

This patch also makes following amendments to core exegesis:
* Added distinction between regular registers aliasing check and
registers used as memory address in instruction.
* Added scratch memory space pointer register.
* General exegesis options were amended:
        * mattr - new option to pass a list of enabled target features

Llvm-exegesis RISCV port is a result of team effort. Below everyone
involved listed.
