drm/xe: improve error capture by dumping vma
Still under XE_SIMPLE_ERROR_CAPTURE, but that prevents heavy instrumentation of user-side code. By sharing the addresses, we can check the content from the user side using a simple application (from the table of pages to the contents of buffers). The error dump fails if the vm lock cannot be acquired.
