[FLINK-31326] Consolidate source scaling logic (#546)

Previous changes removed the requirement for sources to have the pendingRecords metric. This allows to refactor and consolidate the source scaling code. We remove the option to disable scaling sources because the primary motivation was to skip scaling legacy sources which we can achieve without an extra configuration option.

The refactored source scaling logic works like this:

* Modern sources (busy time available)

Scale source based on the busy time up. Add extra capacity if the lag
information, provided by the pending records metric, is available. Otherwise
assume 0 lag. Cap by the maximum number of partitions, if available.

* Legacy sources (busy time unavailable)

Leave the source parallelism unchanged, use the current processing rate as the
target rate downstream.
