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

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.

Global init flag is useful only for once per context initialization.
Correctly set the flag can save the visits to these once per context
calls.

Unify fp16/fp32/fp64 across all platforms. The capabilities indicated by
those flags now refer to both emulated and native-supported (HW) ones:
- Global/local atomic load: HW support on all platforms (handled by native
i16 atomic or) for FP16, FP32 and FP64.
- Global/local atomic store: HW support on all platforms (handled by
native i16 atomic exchange) for FP16, FP32 and FP64.
- Global/local atomic compare/exchange: HW support on all platforms
for FP32.
- Global/local atomic min/max: Emulation support on all platforms for
FP64, HW support on all platforms for FP32, HW support on XE+ platforms
and emulation support on all others for FP16.
- Global atomic add: HW support for PVC+ platforms, emulation support on
all other platforms for FP64, HW support on XE+ platforms and emulation
support on all other platforms for FP32.
- Local atomic add: Emulation on all platforms for both FP64 and FP32.

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 fix is most important for multi command list execution use cases.
It is also benefitial for single command list execution, as driver saves
on loop enters and exits.
Methods handling single command list instead of array of objects are simpler.
Removed loops were at:
- CommandListExecutionContext constructor
- estimateLinearStreamSizeInitial method
- computePreemptionSize method
- collectPrintfContentsFromAllCommandsLists method

Plenty of calls require hw command programming only once per context.
There is no need to visit every method of them every execute call.
Set global init flag only if any of them is true and then visit all of them.
But for regular command list execution it can save time when there is single
global check.

This is number of small tweaks to state cache invalidation:
1. Invalidate if heap was actually created.
2. Check if os context was actually initialized.
3. Heap allocation was actually submitted, as it might attain zero task count
value, when allocation is stored in csr internal storage, as csr wasn't used,
but the csr task count being zero is assigned to heap allocation when stored.
