Lift more weed restrictions (#7611)

# About the pull request

This PR is a follow up to #7363 #7556 and #7535 which have been changing
where xenos are allowed to weed. This should be the final update to
allow xenos weeding capabilities anywhere but OOB and the AI Core
(atleast until marines land then there is a temporary restriction).

Also fixes an oversight where resin walls and doors were not getting
weed killed.

# Explain why it's good for the game

Fixes #7583

# Changelog
:cl: Drathek
code: Added sanity checks for whenever AREA_UNWEEDABLE is used or when
an area is somehow null
balance: All maps have their round start is_resin_allowed restriction
lifted unless out of bounds
maptweak: All maps with OOB areas have now AREA_UNWEEDABLE set to make
the restriction permanent
fix: Resin walls and doors will now properly get weed killed
