[RISCV] Add MC layer support for proposed Bit Manipulation extension (version 0.92) This adds the instruction encoding and mnenomics for the proposed RISC-V Bit Manipulation extension (version 0.92). It is implemented with each category of instruction as its own target feature, with the 'b' extension feature enabling all options. Since this extension is not yet ratified, all target features are prefixed with 'experimental-' to note their status. Differential Revision: https://reviews.llvm.org/D65649
