[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
