Fix killer door textures

[vaguerant]

Workaround to fix #263.

This may not be the ideal solution. #616 proposes reinstating the original N64 object dependency, but that has its own drawbacks, like crashes when using wrong-age equipment.

I think no matter what the solution ends up being, it will probably involve making hotfixes to various behaviors. It's either workarounds for issues caused by the current behavior, or undo object dependency changes and make workarounds for the issues caused by that instead.

Left a comment noting the workaround, ala the similar #615.

EDIT: Additional note:

As far as I know, fake doors only appear in the Fire Temple (where they use the HIDAN [Fire Temple] metal door texture), Spirit Temple and Gerudo Training Ground (where they use the default GAMEPLAY_KEEP wooden door texture).

The killer door object is also set up to handle using the MIZU (Water Temple) and HAKA (Shadow Temple) textures even though they don't seem to occur in those areas. Maybe they do appear in Master Quest, or maybe they were removed from those areas during development, or maybe they were just covering their bases in case they ever did want to use them.

This workaround replicates that original behavior, so fake doors should display with dungeon-appropriate textures if forcibly spawned in those locations.

I'd rather have authentic behaviour, even if it means that Child Link can't use Hookshot and Adult Link can't use Deku Sticks. The proposal in #616 is definitely the right answer. If we really want to keep those special cases, we can load the Adult and Child objects at all times.

since we decided against bringing back authentic object dependency this can go in
