Marc-André Lureau a947cf84c5 system/memory: add RamDiscardManager reference counting and cleanup ...

Listeners now hold a reference to the RamDiscardManager, ensuring it
stays alive while listeners are registered. The RDM is eagerly freed
when the last source and listener are removed, and also unreffed during
MemoryRegion finalization as a safety net.

This completes the TODO left in the previous commit and prevents both
use-after-free and memory leaks of the RamDiscardManager.
