Use generic types to specify square forms of outerProduct.
This reduces our memory footprint slightly (smaller dehydrated data,
fewer IRNodes in the rehydrated GPU module).
This required a small tweak to our built-in types. $squareMat and
$squareHMat are now aligned with our $vec/$genType generics. (The "1x1
matrix" case is explicitly marked as invalid, allowing `float2x2` to
match up with `float2` and `half2x2` to match up with `half2`.)
