Instead of a ConstantBuffer.
HLSL requires that each structure field in a UBO is 16 byte aligned.
WGSL has much looser constraints with its UBO field alignment rules.
Instead generate an array of uint4 vectors, and index into this, much
like we index into [RW]ByteAddressBuffers for SSBOs.
Extend the DecomposeStorageAccess transform to support uniforms too.
This has been renamed to DecomposeMemoryAccess.

And fix issues where global variables would not be emitted unless they were transitively referenced by an entry point.
This change requires crbug.com/tint/697 to be fixed before landing.

Simplifies the emission, and fixes emission of `let` statements in the loop.
Also fix random indenting of intrinsic functions.
