Possibility to make opening GTG a permanent flag

[djevangelia]

This is an implementation of permanent flag open GTG after opening it once. Closes #2011 given that it can be agreed upon settings for it.

Guard opens GTG like normal. In addition to temporary scene flag, a permanent flag (4) is set.
When entering Gerudo Fortress again, guard and gate check for this flag.
If set, guard will offer to throw in jail, and the gate will be open.
Extra check has been added so that the gate does not open as child.

It currently uses dungeon entrance shuffle as setting. Once it's agreed upon what randomizer setting should be used it will be changed.
The flag number was chosen because I could only find that 3 is in use (large gate).

Testing

Tested on Ares recent nightly build and Project64 3.0.1.

For instant Gerudo card:

if (z64_game.common.input[0].raw.pad.dl) {
    z64_GiveItem(&z64_game, Z64_ITEM_GERUDOS_CARD);
}
