  [HLSL] Vector standard conversions (#71098)

HLSL supports vector truncation and element conversions as part of
standard conversion sequences. The vector truncation conversion is a C++
second conversion in the conversion sequence. If a vector truncation is
in a conversion sequence an element conversion may occur after it before
the standard C++ third conversion.

Vector element conversions can be boolean conversions, floating point or
integral conversions or promotions.
