pvr: Reserve space for vdm state for deferred secondary buffer.

Browse source 
For secondary buffer we need to emit additional vdm state along
with additional ppp state words to provide depthbias and scissor
indexes. These are indexes into depthbias and scissor tables.

In vkCmdExecuteCommands we append secondary buffer tables to primary
buffer tables, so the depthbias and scissor indexes change and
need fixing. This is why we need to emit these separatly.
