- For NvRmHeap_GpuMem, we are switching from a carveout to huge pages
obtained from hugetlbfs.
- Allocate a handle from VA using get_user_pages, when allocation is
requested from GPU heap.
- Introduce a new field to indicate that the pages are allocated from
hugetlbfs. This field will be useful while returning the correct heap
while querying the handle params for a handle which was created using
hugetlbfs.
- Update the query heap API for GpuMem heap to return the huge pages
memory values from meminfo.

Add support for Serial Id feature which will be used by Nsight for
buffer tracking purpose. This feature expects a unique serial id per
buffer even if it is shared across multiple client processes.
Add following code:
- Create a new global counter field for serial id in nvmap device.
Initialize it to 0 when nvmap device is initialized.
- Introduce a new field for serial_id in nvmap_handle struct.
- When nvmap_handle is created, assign it's serial_id field with global
counter's value, and increment global counter.
- During NvRmMemQueryHandleParameters return this serial_id associated
with the handle.
- Do not decrement counter for serial_id even after freeing the handle.

In NUMA system, user can request nvmap to allocate from any particular
node using NvRmMem APIs. Add code to request allocation from such
requested node. While allocating pages from page pool, check if those
pages belong to requested NUMA node. In some cases, we may not need to
use NUMA support e.g. in color pages allocation code, we don't need to
use NUMA, as page coloring is needed only for t19x chips.
