  [HLSL][Matrix] Make HLSLElementwiseCast respect matrix memory layout (#184429)

Fixes #184379

Changes the implementation of HLSLElementwiseCast to respect matrix
memory layout.
The new implementation reads from the `LoadList` array in row-major
order as opposed to column-major in the old implementation, which makes
more sense because `LoadList` is always interpreted in row-major order
when read as a matrix.
The writes to the allocation `V` for the destination matrix now respects
the default matrix memory layout.
