radv: add support for non-inverted conditional rendering
By default, our internal rendering commands are discarded
only if the predicate is non-zero (ie. DRAW_VISIBLE). But
VK_EXT_conditional_rendering also allows to discard commands
when the predicate is zero, which means we have to use a
different flag.
