Revert of Reland of [Blink] XMLTreeViewer should load resources from blink_resources.grd instead of relying upon xxd.py… (https://codereview.chromium.org/393213002/)

Reason for revert:
I mistakenly thought a clobber fixed the bot. It was actually the revert. The bot is failing again after the reland.
