target/riscv: Add zext.h instructions to Zbb, removing pack/packu/packh
The 1.0.0 version of Zbb does not contain pack/packu/packh. However, a
zext.h instruction is provided (built on pack/packh from pre-0.93
draft-B) is available.
This commit adds zext.h and removes the pack* instructions.
Note that the encodings for zext.h are different between RV32 and
RV64, which is handled through REQUIRE_32BIT.
