Originally by @kuhar, with cleanup by @bjacob .

Add focused decoded WMMA regressions for RDNA3 packed destination halves, RDNA4 subnormal accumulators, and BF16 factor encoding.
Reuse the matrix input generator and runner, with a small sample of original expected outputs.

This commit only adds tests; the arithmetic implementations are unchanged.

Validation: GCC Release build and 22 focused C++ tests pass at the four-commit stack tip; generator-profile tests also pass.

Stacked on #13813.

Progress towards #13670.

It would help to make the test descriptions identify the expanded scope and capture architecture:

• emulation/rocjitsu/tests/rdna_wmma_float_test.cpp:4: include dense FP16/BF16 packed-half and accumulator regressions in the file summary, which currently mentions FP8/BF8 and mixed formats.
• emulation/rocjitsu/tests/fixtures/float_dot/rdna_f16_samples.h:11: name the sample kWmmaF16Gfx11High (as with kWmmaIu8Gfx11). FP16 WMMA exists on both targets, so carrying the architecture in the identifier makes the captured result's scope visible at its use site.

Addressed the review, including the expanded file summary and kWmmaF16Gfx11High fixture name. The fixture uses the lightweight sample header and is listed in the fixture index. The extra BF16 architecture-contrast case is only a few lines.

Validation at this commit: all 15 focused matrix C++ tests and all applicable pre-commit hooks pass.

The earlier emulation job's reported failures also occur in the base develop job; it stopped with a custom-container error. Fresh CI is running on the updated commit.
