SERVER-48452 Internal readers should default to reading without a timestamp
Removes ReadSource::kUnset in favor of kNoTimestamp as the default
Makes the following behavioral changes to AutoGetCollectionForRead:
* Removes special early-return handling for kNoTimestamp
* Only user or DBDirectClient operations are eligible to read at
kLastApplied.
* Operations only read at kLastApplied when in the SECONDARY state, nothing
else. This means most internal operations that use DBDirectClient do not need
to use a ReadSourceScope to ensure they read at kNoTimestamp.
