Support lazy tuner server

*) Refine code to not use global instance. It makes us easier to debug
reference count.
*) The service will only be started if the tuner feature is declard by
the vendor. So we don't need to check tuner feature and whether tuner
HAL is presented anymore.
*) The service will register its resources to TRM every time when it's
started. The TRM will update its resource mapping accordingly.
*) Use tuner.server.enable to change tuner server to be a normal service
if the HAL is not a lazy HAL.

Bug: 236002754
Test: atest android.media.tv.tuner.cts on both lazy and normal HALs
