RISC-V: Make SHA-256, SM3 and SM4 builtins operate on uint32_t

This is in parity with the LLVM commit a64b3e92c7cb ("[RISCV] Re-define
sha256, Zksed, and Zksh intrinsics to use i32 types.").

SHA-256, SM3 and SM4 instructions operate on 32-bit integers and upper
32-bits have no effects on RV64 (the output is sign-extended from the
original 32-bit value).  In that sense, making those intrinsics only
operate on uint32_t is much more natural than XLEN-bits wide integers.

This commit reforms instructions and expansions based on 32-bit
instruction handling on RV64 (such as ADDW).

Before:
   riscv_<op>_si: For RV32, fully operate on uint32_t
   riscv_<op>_di: For RV64, fully operate on uint64_t
After:
  *riscv_<op>_si: For RV32, fully operate on uint32_t
   riscv_<op>_di_extended:
                  For RV64.  Input is uint32_t and output is int64_t,
                  sign-extended from the int32_t result
                  (represents a part of <op> behavior).
   riscv_<op>_si: Common (fully operate on uint32_t).
                  On RV32, "expands" to *riscv_<op>_si.
                  On RV64, initially expands to riscv_<op>_di_extended *and*
                  extracts lower 32-bits from the int64_t result.

It also refines definitions of SHA-256, SM3 and SM4 intrinsics.
