Add support for push constants
- Proper support for calculating offsets in explicit-layout storage
classes (push constant, uniform, and storage buffer) according to the
Offset, ArrayStride and MatrixStride decorations.
- Plumb a block of push constant data throughout the pipeline
- Implement push constant update commands
