target/mips: Rename sa16 -> sa, bz_df -> bz -> bz_v This 'shift amount' format is not always 16-bit, so name it generically as 'sa'. This will help to unify the various arg_msa decodetree generated structures. Rename the @bz format -> @bz_v (specific @bz with df=3) and @bz_df -> @bz (generic @bz). Since we modify &msa_bz, re-align its arguments, so the other structures added in the following commits stay visually aligned.

target/mips: Convert MSA 3R instruction format to decodetree (part 1/4) Convert 3-register operations to decodetree. Since the 'data format' field is a constant value, use tcg_constant_i32() instead of a TCG temporary. Note, the format definition could be named @3rf_b (for 3R with a df field BYTE-based) but since the instruction class is named '3R', we simply call the format @3r to ease reviewing the msa.decode file. However we directly call the trans_msa_3rf() function, which handles the BYTE-based df field.
