Fix missing border update after Image blit

ANGLE uses image blit to generate mipmaps so, for cubemaps, a border update is required after we blit into an image so that the cube's border are still seamless when using lower mip levels. Fixes WebGL Conformance Test: conformance/textures/misc/texture-size.html Bug: b/154620294 Change-Id: I22daf60afd9143c52a57c67ae0039eb49be4f1ca Reviewed-on: https://swiftshader-review.googlesource.com/c/SwiftShader/+/44990 Presubmit-Ready: Alexis Hétu <sugoi@google.com> Kokoro-Result: kokoro <noreply+kokoro@google.com> Tested-by: Alexis Hétu <sugoi@google.com> Reviewed-by: Nicolas Capens <nicolascapens@google.com>
