When copying the secondary command buffer's deferred control stream
to the main stream we have to first allocate space in the main
stream. In case the allocation failed we were attempting to
memcpy() to a NULL destination causing a NULL dereference.
This fixes CID 1515977.

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.

Each time a word is emitted the appropriate bit in the mask is

Previously `struct pvr_emit_state` was used to keep track of which
state update required emitting and the header was setup based on that.
This commit removes it so that we're instead setting up the header as
we go and we can emit it directly instead of decoding it based on the
emit_state (which is almost identical but with a few missing fields).
This commit also changes pvr_emit_ppp_state() so that each control
stream word is packed/emitted on its own instead of everything
being nested within the header pack. Making the code a bit easier

opportunity to simplify how the tex type is determined when packing
