operation will be blocking (lock on config.file)

Add "DumpZEBin" debug flag. When this flag is enabled, Zebin will be
dumped to a .elf file (with appropiate suffix, in case such file has
been dumped before).

Add mechanism to increase direct submission timeout up to a maximum
value when no new submissions were made since last sleep.
This should help in workloads that have delays between iterations larger
than current direct submission controller timeout.

In the case of mtl+ platforms, the returned config value
should equal the hardware ip version value.
This change fixes situations where some config has not been
added and in this case we returned an unknown value.

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.

When state base address tracking is enabled and command list use private heaps
then command list at destroy time must calls all compute CSRs that were using
that heap to invalidate state caches.
This allows new command list to reuse the same heap allocation for different
surface states, so before new use cached states are invalidated.

It is possible that a module has so many kernels that the 4GB limit of
GPU VA is depleted when each kernel allocates a 64 KB page for its own
ISA. In such case, propagate the ZE_RESULT_ERROR_OUT_OF_DEVICE_MEMORY to
the API caller to indicate the actual problem.
Currently such scenario is not detected, the execution advances a bit
further and the following crashes do not let the user to easily
understand what happened.
