This commit adds RISC-V C API feature bit metadata for several extensions including supm, zicntr, zihpm, zfbfmin, zvfbfmin, zvfbfwma, zicbom, zaamo, zalrsc, zabha, zalasr, zicbop, and zicfilp. This metadata enables the compiler to detect the presence of these extensions. The patch incorporates information from riscv-c-api-doc PR #185 but does not add ISA extension support or new runtime probing capabilities directly.
