all: add GORISCV64 environment variable
cmd/go: add rva23u64 as a valid value for GORISCV64
The RVA23 profile was ratified on the 21st of October 2024. https://riscv.org/announcements/2024/10/risc-v-announces-ratification-of-the-rva23-profile-standard/ Now that it's ratified we can add rva23u64 as a valid value for the GORISCV64 environment variable. This will allow the compiler and assembler to generate instructions made mandatory by the new profile without a runtime check. Examples of such instructions include those introduced by the Vector and Zicond extensions. Setting GORISCV64=rva23u64 defines the riscv64.rva20u64, riscv64.rva22u64 and riscv64.rva23u64 build tags, sets the internal variable buildcfg.GORISCV64 to 23 and defines the macros GORISCV64_rva23u64, hasV, hasZba, hasZbb, hasZbs, hasZfa, and hasZicond for use in assembly language code.
