If several kernel heaps are sharing the same page then use a temporary
buffer to collect all of them and transfer to memory in one shot.
Previously there were several transfers performed (one per kernel) and,
observably, they happened not to be immediately effective at times.

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.

Enabling on pvc after patch in igc.
Enabling only for JIT kernels because AOT could have been compiled with
IGC older than required.

- refactor state base address programming - program address and size
together, set max size at the beginning due to lack of Enable flag
- set GpuBase in WddmAllocation when external heap is used
- return max ssh required size from kernelInfo or based on stateful args

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.
