radv: exclude dynamic vertex input stride for the late scissor workaround

Browse source 
RADV_DYNAMIC_VERTEX_INPUT_BINDING_STRIDE doesn't emit any context
registers, so it can be excluded for the late scissor workaround to
avoid re-emitting scissors all the time it's dirty.

This fixes a performance regression noticed with Cyberpunk on Vega10,
but other games are likely affected too. The late scissor workaround is
only applied on Raven/Vega10.

Closes: https://gitlab.freedesktop.org/mesa/mesa/-/issues/13828
Fixes: d7f401c2bb ("radv: bind the vertex binding strides like a normal dynamic state")
