drm/xe: Retain vma flags when recreating and splitting vmas for madvise

When splitting and restoring vmas for madvise, we only copied the
XE_VMA_SYSTEM_ALLOCATOR flag. That meant we lost flags for read_only,
dumpable and sparse (in case anyone would call madvise for the latter).

Instead, define a mask of relevant flags and ensure all are replicated,
To simplify this and make the code a bit less fragile, remove the
conversion to VMA_CREATE flags and instead just pass around the
gpuva flags after initial conversion from user-space.
