tests/tcg: target/mips: Include isa/ase and group name in test output

For better appearance and usefullnes, include ISA/ASE name and
instruction group name in the output of tests. For example, all
this data will be displayed for FMAX_A.W test:

| MSA | Float Max Min | FMAX_A.W |
| PASS: 80 | FAIL: 0 | elapsed time: 0.16 ms |

(the data will be displayed in one row; they are presented here in two
rows not to exceed the width of the commit message)

tests/tcg: target/mips: Add utility function reset_msa_registers()

Add function reset_msa_registers() and utilize it in each MSA test.
This is needed to ensure independency of test results on the state of
MSA registers before test execution. This also allows for correction
of tests for VSHF* instructions, that are now independent on the
previous state of MSA registers.

target/mips: Amend and cleanup MSA TCG tests

Add missing bits and peaces of the tests of the emulation of certain
MSA (non-immediate variants): some tests were missing two last cases;
some instructions were missing wrappers; some test included wrong
headers; some tests were missing altogether; updated some copywright
preambles; do several other minor cleanups.
