Region 0: Ranges remain in SMEM with only PTE updates.
Region 1: Ranges migrate to VRAM with corresponding PTE updates.
Madvise Ioctl:

Provides a user API to assign attributes like pat_index, atomic
operation type, and preferred location for SVM ranges.
The Kernel Mode Driver (KMD) may split existing VMAs to cover input
ranges, assign user-provided attributes, and invalidate existing PTEs so
that the next page fault/prefetch can use the new attributes.

v2
- Address comments from Matt B
- Add atomic handling
- Rebase
