Allocating vector backing storage on stack makes it allocated
together with the whole command list object.
So no second use of heap for the state changes vector data.

State changes are kept in vector that is reserved for 32 state changes in
single execute call. It can be useful when multiple commands are executed
at once.
More workload use single or few command lists and so creation time of command
queue could be more benefitial.

Single command list object can be passed multiple times to the execution
command list.
Not all command list instances might require dynamic preamble, as it depends
what state is before particular command list instance.
Correctly assign the particular instance of command list to state transition.

Before state transition was done twice, 1st time for estimation, 2nd time for
dispatch.
Now state transitions only during estimation and required state is saved then.
Commands are dispatched only when command list and property are marked to
dispatch.
During regular workload submission transition is performed only once and it
should be benefitial to reduce host overhead.
