  [RISCV] Add groupid/bitmask for RISC-V extension (#94440)

Base on https://github.com/riscv-non-isa/riscv-c-api-doc/pull/74.

This patch defines the groupid/bitmask in RISCVFeatures.td and generates
the corresponding table in RISCVTargetParserDef.inc.

The groupid/bitmask of extensions provides an abstraction layer between
the compiler and runtime functions.
