Ben Clayton e4fd4a2ecd test/intrinsics/gen: Use '0' for level parameters 
The level parameter needs to be zero for a number of texture overloads.
Bodging the template to emit 0 instead of 1 for any `level : i32` parameter is the easiest fix here.

Ben Clayton 51b9da45c8 writer/hlsl: Fix level packing for textureLoad() 
This was spectacularly broken. Caught by CTS.

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.

This is required to generate valid MSL code, and will soon be
validated by Tint too.

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.
