Skip having to trigger Zelda escape cutscene

[HylianFreddy]

Mark the Zelda escape cutscene as watched when obtaining the 3rd spiritual stone, so that the next time the player visits Hyrule Field, the ocarina will already be in the moat.

More specifically:

• if the 3rd stone is obtained outside HF or as adult, the cutscene will immediately be set as watched;
• if the 3rd stone is obtained in HF as child, the drawbridge will wait for the player to approach (this is unchanged behavior), then
  • if the player approaches, the behavior is unchanged, so the cutscene triggers and the area reloads in the "ocarina in moat" layer;
  • if the player leaves HF, the cutscene will be set as watched by the bridge destroy function;
  • if the player savewarps, the behavior is unchanged, the cutscene will still need to be triggered.
