Revert "Enable GrTessellationPathRenderer by default"

This reverts commit 6ea387e7c7.

Reason for revert: valgrind failing

Original change's description:
> Enable GrTessellationPathRenderer by default
>
> Moves GrTessellationPathRenderer to the end of the chain and enables
> it by default.
>
> Also updates nvpr to not draw volatile paths. The tessellator is much
> faster at these.
