This gives a baseline of how many transposes are inserted in the graph for a number of important decompositions. Also updates test_high_rank_permute_view_invariants to use the same way of counting tranposes instead of a custom solution.

Pull request overview
Adds a new Arm-backend test suite to baseline how many TOSA TRANSPOSE ops are inserted for a range of decompositions and memory formats, and aligns an existing high-rank permute/view fuzz test with the same counting mechanism.
Changes:
- Introduce
test_transpose_counts.pywith a broad set of FP transpose-count baselines (including channels-last variants with targeted xfails). - Refactor
test_high_rank_permute_view_invariants.pyto usepipeline.count_tosa_ops()instead of custom.tosaartifact parsing.

| backends/arm/test/misc/test_transpose_counts.py | New transpose-count baseline suite for FP lowering (standard + channels-last cases). |
| backends/arm/test/misc/test_high_rank_permute_view_invariants.py | Switch high-rank permute/view fuzz test to the shared transpose-count mechanism and remove direct TOSA flatbuffer invariant parsing. |
