Add a config parameter for the CanonicalizeEntryPoint transform that selects between emitting builtins as parameters (for MSL) or struct members (for HLSL). This fixes all of the shader IO issues in Tint's E2E tests for MSL. Fixed: tint:817 Change-Id: Ieb31cdbd2e4d96ac41f8d8515fd07ead8241d770 Reviewed-on: https://dawn-review.googlesource.com/c/tint/+/53282 Kokoro: Kokoro <noreply+kokoro@google.com> Reviewed-by: Ben Clayton <bclayton@google.com> Commit-Queue: James Price <jrprice@google.com>
