  [HLSL][Matrix] EmitFromMemory when emitting load of vector and matrix element LValues (#178315)

Fixes #177712

The MatrixElt and VectorElt cases of `EmitLoadOfLValue` did not convert
the scalar value from its load/store type into its primary IR type like
the other cases do, which caused issues with HLSL in particular which
requires bools to be converted to and from i32 and i1 forms for its
load/store and primary IR types respectively.

This PR fixes the issue by applying `EmitFromMemory` to the loaded
scalar.
