In L0 its not possible to track objects relations. For example CmdList
may be removed before Event.
In such case, Event needs to safely skip unregister call, without
accessing CmdList/CmdQueue object.

Immediate command list can use internal command queue.
Immediate command list then uses variable start offset and it does not
work with primary batch buffer.

This optimization removes pipeline select from command list preamble
and presented to command queue for necessary state update.
Code is disabled by default and available under debug key.

Front end estimation use internal loop for command list browsing and
estimation of each command list.
This refactor moves internal loop into external execution, so command list
browsing in loop can be shared by all state commands.
This refactor - sharing loop - will correct performance of each added state
estimator.

This change gives fine grain control over front end configuration for each
kernel.
As it gives possible to inject FE command in command queue and return to exact
place in command list.
Programming commands in queue makes patching commands in command lists
not needed as that operation is costly.
And it allows to program context information for each command list too.
