- Adds Prepend function to LinkedList to avoid directly using the insert functions on the LinkNodes. (And tests for this as well.) - Adds ApiObjectList class for tracking lists of objects for destruction. - Renames and virtualizes some tracking interfaces so that they can be overriden for the TextureView/Texture cases. - Removes explicit destroying of TextureViews from Device since destroying Textures will destroy TextureViews now. Fixed: dawn:1355 Change-Id: I3522383ea7724d6e41ac0c805793a6c34d9bec27 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/101762 Reviewed-by: Austin Eng <enga@chromium.org> Commit-Queue: Loko Kung <lokokung@google.com> Kokoro: Kokoro <noreply+kokoro@google.com>
