Correct createConstructionSite structureType params

[sparr]

Brief Description

Update createConstructionSite param types to specify only buildable structures, allow all buildable structures, not just spawns. I'm not sure how calls for non-spawn structures were passing type checks previously. This seems like a correct update, but because tests weren't failing before I'm not sure how to verify that I haven't made some mistake here. I also made a few related corrections, narrowing one of the signatures from the overly broad type that includes non-buildable structures.

Checklists

• Test passed
• Coding style (indentation, etc)
• Edits have been made to src/ files not index.d.ts
• Run npm run compile to update index.d.ts

A couple of those createContructionSite are type-override to limit the applicability of the name parameter to only spawns. That's why it's either a structure constant with no name, or a STRUCTURE_SPAWN and an optional name.

Thanks, I missed that. Updated commit and PR description with just the other fix.
