  -----------
  [ORC] Add withResourceKeyDo method to ResourceTracker.

This method behaves the same as MaterializationResponsibility::withResourceKeyDo
(which now forwards to the new method): It locks the session while providing
access to the ResourceKey associated with the tracker.

Adding this method to ResourceTracker allows resources to be allocated and
tracked for a given MaterializationUnit prior to that MaterializationUnit being
materialized. E.g. Platforms can now track and remove initializers and other
symbols.

  Log Message:
  -----------
  [ORC] Add JITDylib argument to ResourceManager notify-removing/transferring ops.

In some cases it's helpful to group trackers by JITDylib. E.g. Platform classes
may want to track initializer symbols with a `JITDylib -> Tracker -> [ Symbol ]`
map. This makes it easy to collect all symbols for the JITDylib, while still
allowing efficient removal of a single tracker. Passing the JITDylib as an
argument to ResourceManager::notifyRemovingResources and
ResourceManager::notifyTransferringResources supports such use-cases.
