Translator: Reorganize files This change makes the translator files more organized by: - Grouping files that are specific to a certain output under their own directory, - Moving transformations under tree_ops - Removing Direct from metal translation now that that SPIR-V Cross path is removed Bug: angleproject:6394 Change-Id: Iaf5bb8d5604b84748dece029821b1f77b2813967 Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/4678780 Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org> Reviewed-by: Geoff Lang <geofflang@chromium.org>
