Treat glBeginQuery* and glEndQuery* commands the same as glDraw*
commands, generating a hierarchy. This results in vkCmdBeginQuery and
vkCmdEndQuery commands being nested under gl*Query*, instead of being
a peer of glDraw* commands.
This change necessitated plumbing some of the existing "end" path to
return angle::Result.
