The class Kernel is abstract and as such it should not have any members.
Move its members to sharedState as this is what they represent.

So far, there is a separate page allocated for each kernel's ISA within
`KernelImmutableData::initialize()`. Apparently the ISA blocks are often
much smaller than a 64k page, which leads to poor memory utilization and
was even observed to cause the device OOM error if a single module has
several keys.
Improve the situation by reusing the parent allocation (owned by the
module instance) for modules, which kernel ISAs can fit together within
a single 64k page. This improves the memory utilization on a single
module level.

- Given a Base Pointer passed into Get Peer Allocation, then the base
pointer is used in the map of the new allocation to the virtual memory.
- Enables users to use the same pointer for all devices in Peer To Peer.
- Currently unsupported on reserved memory due to mapped and exec
resiedency of Virtual addresses.

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.

- apply revelant flags only on platforms supporting these flags
- update command list preemption level when supported
- use actual kernel preemption level to program interface descriptor data

- 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
