NFC: Extract HLSLBool_t and HLSLHalf_t into shared HLSLTestDataTypes.h

Move shared HLSL test type wrappers out of LongVectorTestData.h into a
common header that both LongVector and LinearAlgebra tests can include.
Also adds HLSLNorm_t, F8E4M3_t, and F8E5M2_t wrappers for full SM 6.10
linalg ComponentType coverage.

LongVectorTestData.h retains backward-compatible using declarations.
