Limit the amount of times compare_exchange_weak is called,
to avoid issues with contention when multiple cpu cores request
the same address.

This change extends the logic of opening IPC
memory handles and fills the gap between this
logic and allocation of USM device buffers.
When HEAP_EXTENDED is available, then it is
preferred.

Unrecoverable abort will be invoked when drm ioctls fail during
device destruction.
Remove abort for case where i915 is unbinded.

This change makes that drm file is opened in nonblocking mode for prelim
kernels. In such case when calling exec buffer ioctl and get
EAGAIN (aka EWOULDBLOCK) we may return error to API level

This change replaces unneeded copying of std::vectors
with usage of const references. Furthermore, it adds
reserve() call before filling the container via push_back().

Improve performance by binding the command buffer together with other
allocations if VM_BIND feature is available. Remove the legacy
flag PassBoundBOToExec from DebugManager to simplify the logic.
Adapt unit tests and reuse handy macros to generate proxy mock-methods.

With this change, module's data sections will be allocated in USM device
pool instead of SVM or USM shared.

We want to return error code to the application instead of aborting when
we are not able to make more memory resident.
