This CL implements f16 in uniform and storage address space, allowing using f16 types in uniform and storage buffers on all backends. Tint uint tests and Dawn E2E tests are added to validate the f16 types work as expected. Bug: tint:1473, tint:1502 Change-Id: I15e3de1033d3727f2ea33f4657f682c5f13c2153 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/106320 Kokoro: Kokoro <noreply+kokoro@google.com> Commit-Queue: Zhaoming Jiang <zhaoming.jiang@intel.com> Reviewed-by: Ben Clayton <bclayton@google.com>
