[PATCH i-g-t v2 36/66] tests/xe_eudebug: Test multiple bo sizes

[Christoph Manszewski <christoph.manszewski@intel.com>]

From: Jonathan Cavitt <jonathan.cavitt@intel.com>

Extend the basic vm access tests to allow for specifying the target bo
size per bo in the bind list. The size still has to be at least the
minimum, but can be overwritten to be larger.

Make sure that the vm is unbound during bind list destroy, to avoid
overlapping vmas.
