Implement EGLImage external texture API for GL.
Tests are based on the IOSurfaceWrappingTests. Sampling tests are not implemented, since they would require support for the samplerExternalOES sampler type in WGSL. Bug: chromium:1205155 Change-Id: Icc114eaf6efaee93f1b8486e615f0fd307f23080 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/50201 Commit-Queue: Stephen White <senorblanco@chromium.org> Reviewed-by: Corentin Wallez <cwallez@google.com> Reviewed-by: Corentin Wallez <cwallez@chromium.org>
