HLSL-IR: Fix texture Sample and SampleLevel return type on depth textures HLSL's texture Sample and SampleLevel functions return a vector, and we must swizzle the first component when sampling a depth texture. Fixes 6 failing e2e tests. Bug: 372746408 Change-Id: I9b4e63395386e7db54abfe640f24a85e95a0f803 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/210535 Reviewed-by: James Price <jrprice@google.com> Commit-Queue: Antonio Maiorano <amaiorano@google.com>
