lima: Implement lima_resource_get_param() callback

Browse source 
Currently stride, offset, modifier is obtained by invoking
lima_resource_get_handle() with WINSYS_HANDLE_TYPE_KMS.

Before commit 47f000c170 this path was working. Obtained handle
was simply ignored by DRI frontend and only requested data used.

After commit 47f000c170 such requests started to fail when
DRI is initialized using KMSRO and resource has no scanout data.

When lima_resource_get_param() is implemented, it will be used in
a first place to obtain resource data.

Fixes: 47f000c170 ("lima: fail in get_handle(TYPE_KMS) without a scanout resource")
