Chris B a29afb754f [HLSL] Allow truncation to scalar (#104844) ...

HLSL allows implicit conversions to truncate vectors to scalar
pr-values. These conversions are scored as vector truncations and should
warn appropriately.

This change allows forming a truncation cast to a pr-value, but not an
l-value. Truncating a vector to a scalar is performed by loading the
first element of the vector and disregarding the remaining elements.

Fixes #102964
