Add a cap to allow coverage counting or not

We don't want to just disable the "ccpr" path renderer anymore (or
whatever it should be called), because we are adding an MSAA
implementation. This new cap will eventually tell ccpr whether it can
use coverage counting, or if it should just use the MSAA impl.
