target/mips: Remove one MSA unnecessary decodetree overlap group
...
Only the MSA generic opcode was overlapping with the other
instructions. Since the previous commit removed it, we can
now remove the overlap group. The decodetree script forces
us to re-indent the opcodes.
Diff trivial to review using `git-diff --ignore-all-space`.

Convert 3-register operations to decodetree.
Per the Encoding of Operation Field for 3R Instruction Format'
(Table 3.25), these instructions are not defined for the BYTE
format. Therefore the TRANS_DF_iii_b() macro returns 'false'

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.
