Previously std::once_flag was assigned per map:
std::unordered_map<ContextId, std::unique_ptr<SipKernel>> which was
incorrect and caused the situation in which SipKernel is allocated only
on 1 context and was skipped for other contexts, so we ended up with
only one allocation regardless of the number of contexts.
This change assigns std::once_flag for each allocated SipKernel.

This change is part of performance feature to start command list batch buffers
as primary.
Implicit Scaling sometimes require to jump over control section and these jumps
must maintain the same level of batch buffer as the whole command list.

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

This change adds space reservation in command list for returning batch buffer
start hw command.
Primary batch buffer can be run from direct submission or from KMD call and
must be aligned to required size.
Ending patch for batch buffer start must be in the last command buffer of the
command list.

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.

On clCreateKernelsInProgram API call, we do not propagate potential
error from MultiDeviceKernel::create function. User would not know that
i.e. out of 4 kernels, only 3 were created succesfully.
- Propagate error returned from MultiDeviceKernel::create function to
API call
- In case of a failure on kernel creation, release all resources for the
already created ones and return empty array (nullptrs).

This feature is part of performance improvement to dispatch and start
command buffers as primary batch buffers.
When exhausted command buffer is closed, then reserve exact space for chained
batch buffer start and bind it to the next command buffer.
When closing command buffer, then save ending pointer and
reserve aligned space.
