Ben Clayton c8434889d8 writer/hlsl: Swizzle depth texture intrinsics 
HLSL usually implicitly casts a vector down to a scalar, but this breaks when passing the vector to RWByteAddressBuffer.Store (for DXC only).

Ben Clayton 5d2f34ecf2 writer/hlsl: Simplify emission logic, clean up output 
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.

James Price 0f1efe04c3 writer/msl: Fix texture intrinsic generation 
Wrap the texture expression in parentheses when it has lower
precendence than the function call operator.

Cast integer coordinates to unsigned integers as required by MSL.

Ben Clayton b07a7cead6 [tools]: Generate intrinisic test cases 
Add test/intrinsics/intrinsics.wgsl.tmpl that generates a vast set of intrinsic overload permutations into test/intrinsics/gen/...

Add expected output for all of these, including 'SKIP' headers for those that currently fail.
