Debugger: More memory management fixes.

DwarfImageDebugInfo:
- Type name/info entries weren't being freed properly.

BaseUnit:
- The array of entries itself was being destroyed, but not the actual
  objects. Consequently none of the DIE objects were ever being freed.

CfaRuleSet:
- The register rules array wasn't being freed.

FileManager:
- References to entries weren't being released. Some more work remains to be
  done here though, as a subset of these objects still have a non-zero ref
  count in the end.
