Fix IR layout of 3-element vectors in cbuffers for -fvk-use-dx-layout (#7282)
* Better handling for 16-byte boundary of d3d cbuffer
Fixes #6921
D3D cbuffers have slightly different packing rules that allow packing
vectors into a 16-byte slot at element alignments, except when
a field would cross a 16-byte boundary. In that case, we need to
realign the field to the next 16-byte boundary.
In particular, this impacts vec3s, which are not a power of two in
size and thus require slightly different alignment logic, compared to
std430 and std140. (Example: a float and float3 should fit together in
that order in a single slot.)
Adds test cases.
Adds documentation page for GLSL target
