Merge pull request #20011 from Developer-Ecosystem-Engineering:3.4 
Improve performance on Arm64

* Improve performance on Apple silicon

This patch will
- Enable dot product intrinsics for macOS arm64 builds
- Enable for macOS arm64 builds
- Improve HAL primitives
  - reduction (sum, min, max, sad)
  - signmask
  - mul_expand
  - check_any / check_all

Results on a M1 Macbook Pro

* Updates to #20011 based on feedback

  - Removes Apple Silicon specific workarounds
  - Makes #ifdef sections smaller for v_mul_expand cases
  - Moves dot product optimization to compiler optimization check
  - Adds 4x4 matrix transpose optimization

* Remove dotprod and fix v_transpose

Based on the latest, we've removed dotprod entirely and will revisit in a future PR.

Added explicit cats with v_transpose4x4()

This should resolve all opens with this PR

* Remove commented out lines

Remove two extraneous comments
