We may get build bustages for fuzzer/asan build without this change: `member access into incomplete type 'nsPluginElement'`. nsMimeTypeArray.h forward-declares the `nsPluginElement` type, so it's not supposed to have any code that calls methods on instances of that type. The `do_AddRef` inline function internally calls `AddRef` on the passed-in thing, so we need to move that to the .cpp file which has the actual type definition available.
