drm/xe: Add properties line to VM snapshot capture

Add properties line to VM snapshot capture which includes additional
information about VMA being dumped. This is helpful for debug purposes
but also to build a robust GPU hang replay tool.

The current format is:

[<vma address>]: <permissions>|<type>

Permissions has two options, either "read_only" or "read_write".

Type has two options, either "userptr" or "bo".
