- change the way we handle blocked commands.
- instead of allocating CPU pointer and populating it with commands, create
real IndirectHeap that may be later submitted to the GPU
- that removes a lot of copy operations that were happening on submit time
- for device enqueue, this requires dsh & shh to be passed directly to the
underlying commands, in that scenario device queue buffers are not used

- This removes Instruction Heap allocation from enqueue path
- Blocked path is handled as well
- Heap is no longer allocated on demand it is bind to kernelInfo.

- read only memory cannot be used for allocation,
Oses cannot create graphics alocation for such memory
- if memory allocation fails for host_ptr passed
to enqueueWrite calls, then try doing new allocation
and copy host_ptr on cpu

- Dont make cpu/gpu writes on read-only unmap
- Read/Write on limited map range only
- Overlaps checks for non read-only maps
- Fixed cmd type on returned event

When queue is blocked on non-blocking call, map operation is added to
waitlist dependencies. Returning slice/row pitch for map image was skipped

- account for initial setting (when set mode was equal to initial(Disabled))
estimate size in cmdStreamCS, program MMIO

- Instruction heap is currently heavily used as every kernel copies ISA into
it.
- It dries out very fast and each change to new heap requires whole pipeline
drain that prevents concurrency
- Problem is even larger when sip kernel is used as it limits the total heap
size
- In order to maximize heap re-use and to limit the count of pipeline drains
this change introduces new minimal size for instruction heap 512 KB.

Fixing InterfaceDescriptor programming for
blocked commands when MidThread preemption is
enabled
Additionally, fixing couple of tests that block
global preemption enabling in ULTs

- Prevents destruction of MemObj while it may still be in use.
- Add UNRECOVERABLE to check whether object is deleted while having
dependencies, fix all problems is tests due to that fact.
- Fix special queue setting, clean interfaces.

- When command queue is blocked, all heaps are being stored in temporary
allocations, command buffers are being pre-programmed, heaps are being set
on those temporary allocations with the assumption that all heaps start with
offset 0.
- Problem was when the actual submissions happened, all those temporary heaps
were just copied to appended command queue heaps, so when something was there
then new stuff was copied right after it. It means that all state was
incorrect as the offsets are not valid anymore and will point to wrong
location.
- This change releases command queue heaps when blocked command is being
submitted to make sure they will be programmed with the proper offset in newly
allocate command queue heap.

- This causes event tree update if virtual event is holding commands or
callbacks
- That causes race between other threads that may be updating the tree
