etnaviv: add stride, offset and modifier to resource_get_param

etnaviv: add stride, offset and modifier to resource_get_param

Prior to this commit, the stride, offset and modifier were fetched
via WINSYS_HANDLE_TYPE_KMS. However we can't make such a query
succeed if the buffer couldn't be imported to the KMS device.

Instead, extend the resource_get_param hook to allow users to fetch
this information without WINSYS_HANDLE_TYPE_KMS.
