Command list batch buffers should be chained when no dynamic or global preamble
is present in command queue.
Return to command queue, when preamble is required.
Chain last command list to the command queue epilog.
Provide first command list batch buffer to KMD/ULLS when no command queue
preamble.

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.

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.

This is small optimization to replace virtual call and retrieved struct with
cached value.

- printf used in kernel is printed on synchronize() call, if
hang is detected - printf buffer was not printed immediately but
only when Kernel was destroyed
- this change adds copying printf buffer with internal engine
(whenever available) right after hang detection on
CommandQueue::synchronize() call

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.
