Revert of Make NVPR a GL context option instead of a GL context (patchset #2 id:20001 of https://codereview.chromium.org/1448883002/ )
Reason for revert:
BUG=skia:4609
skbug.com/4609
Seems like GrContextFactory needs to fail when the NVPR option is requested but the driver version isn't sufficiently high.
