drm/tyr: use shmem GEM object type in TyrDrmDriver

Browse Source 
Tyr buffer objects are shmem-backed, so the driver should use
drm:💎:shmem::Object<BoData> as its GEM object type instead of the base
drm:💎:Object<BoData> type.

Switching to the shmem GEM object type matches how Tyr allocates and
manages its buffer objects, and uses the shmem-specific GEM abstraction
provided by the DRM Rust bindings.

Select RUST_DRM_GEM_SHMEM_HELPER to ensure the required helpers are
available when DRM_TYR is enabled.
