[PATCH v4 02/20] RISC-V: Add bitmap reprensenting ISA features common across CPUs

This patch adds riscv_isa bitmap which represents Host ISA features common across all Host CPUs. The riscv_isa is not same as elf_hwcap because elf_hwcap will only have ISA features relevant for user-space apps whereas riscv_isa will have ISA features relevant to both kernel and user-space apps.
