Calculate available memory for usm device reuse based as (total device
memory - used memory) * fraction for reuse.
Use sys mem allocs for devices without local memory.

Add tracking of memory used for usm reuse mechanism when multiple cl
contexts are used.
Tracking for device added to NEO::Device, for host added to
NEO::MemoryManager.
This fixes usm reuse using x% of memory per each context instead of
globally.

if limiting, disable device usm reuse (set max size to 0)
do not reserve vector for allocation infos if reuse is disabled

Allocations over a certain size will be checked for memory utilization
when chosen for reuse.
If utilization is below a threshold, they will not be reused.

In case of indirect allocations, we don't really know
their task count because we can't track their true usage
on GPU.
In case of non-blocking free, don't wait for latestSentTaskCount.

Do not put into usm reuse if is internal.
Set new isInternalAllocation flag for globals allocations.
Use actual size on device for tracking memory usage.

Allocating global surface is expecting that the usm allocation is zeroed
out. Reusing allocations can be filled with junk data and this caused
errors.

Query system total memory size and limit usm host allocation recycle to
use at most x%.
x is read from ExperimentalEnableDeviceAllocationCache for device and
ExperimentalEnableHostAllocationCache for host.

EnableDeviceUsmAllocationPool and EnableHostUsmAllocationPool for device
and host allocations respectively.
Pool size will be set to flag value * MB.
Allocation size threshold to be pooled is 1MB.
Pools are created per context.

Move code out to base class. This will allow to use the sorted vector
class with different values than only SvmData.
