Revert "Make copyTexImage2D robust when source area is out of bounds"

This reverts commit e1e6f294. Reason for revert: This fix is incorrect, it ends up being a noop. Reverting this first before landing a different fix. Original change's description: > Make copyTexImage2D robust when source area is out of bounds > > Whenever the source area of the texture being copied is out of > bounds and robust resource init is enabled, it is necessary to > clear the invalid portion of the source area to 0 in the copy > operation. > > Bug: angleproject:3930 > Change-Id: If1605b917097006c37e7d59c66babbc32d0ba6d8 > Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2378004 > Reviewed-by: Geoff Lang <geofflang@chromium.org> > Reviewed-by: back sept 10 - Jamie Madill <jmadill@chromium.org> > Commit-Queue: Alexis Hétu <sugoi@chromium.org> TBR=sugoi@chromium.org,geofflang@chromium.org,jmadill@chromium.org,sugoi@google.com # Not skipping CQ checks because original CL landed > 1 day ago.
