Host usm and device usm for igfx checks system memory usage.
Device usm for dgfx checks local memory usage.
If used memory is above limit threshold:
- no new allocations will be saved for reuse
- cleaner will use shorter hold time of 2 seconds
- cleaner will free all eligible allocations, regardless of async
deleter thread having work
Motivation: in case of gfx memory being full, making resident new
allocations will require evictions which leads to massive slowdown on
enqueue calls.
This change aims to minimize cases where extra memory usage from usm
reuse mechanism leads to above situation.

Add resetBuiltins helper function to MockRootDeviceEnvironment.
Update tests to use the new function whenever builtins unique pointer
is reset to ensure that sip kernels are properly freed.

Move ulls controller thread stopping to execution environment
destructor. This removes the vptr race from ulls controller destructor.
Put tests that are actually running the ulls controller into multi thread
tests.
That way they are compiled with thread sanitizer and removes the
variable test time from traditional ULTS.

Add support for configuring ccs mode for all applicable devices
before KMD is loaded.
Use ZEX_NUMBER_OF_CCS to configure ccs mode.
Format is as follows:
ZEX_NUMBER_OF_CCS=NumberOfCcs i,e Setting ZEX_NUMBER_OF_CCS
to 4 sets ccs mode to 4 for all devices for which configuration
is supported.

Added getDefaultDeviceHierarchy call that describes default device
hierarchy for a gfx core. Refactored L0 and OCL paths to use this
value by default and override this value when user sets
ZE_FLAT_DEVICE_HIERARCHY environment variable or
ReturnSubDevicesAsApiDevices debug key.
Updated ReturnSubDevicesAsApiDevices to force COMPOSITE device hierarchy
when set to 0.

- When communicating with the Metrics Libraries, if one is using a
specific sub device, then the correct physical sub device index and
number of sub devices must be used.
- When Affinity Mask is set, this hierarchy information is lost,
therefore the sub device hierarchy data is stored in a map to each
"device" to be returned to the user allowing for the correct sub device
information to be passed to the metrics library.
