TmpFile can now be supplied an optional file extension. This change was motivated by validation work using the XCode SDK Metal compiler, which expects a source file to end with the ".metal" extension. See https://developer.apple.com/documentation/metal/libraries/understanding_the_metal_shading_language_filename_extension Bug: tint:535 Change-Id: I5d44baa20ba350530ace46569e238c4627135e51 Reviewed-on: https://dawn-review.googlesource.com/c/tint/+/45720 Kokoro: Kokoro <noreply+kokoro@google.com> Reviewed-by: Ben Clayton <bclayton@google.com> Commit-Queue: Arman Uguray <armansito@chromium.org>
