Intel ppgtt-model requires memory addresses to be aligned by page size.
Test explores cases with cached memory-buckets and sizes above cached.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=106997
Tests: 24839663a402 (intel/ppgtt: memory address alignment)
Tests: a363bb2cd0e2 (i965: Allocate VMA in userspace for full-PPGTT systems.)
