SkyratBot 20d03b6483 [MIRROR] Avoid creating string list of turf platings, rename some of the APIs, and improve focused test support - 160ms+ (more on prod) of init savings [MDB IGNORE] (#18357)
* Avoid creating string list of turf platings, rename some of the APIs, and improve focused test support - 160ms+ (more on prod) of init savings (#72056)

Looking at some stuff that uses `Join` right now as targets, this one's
pretty straight forward.

`/turf/open/floor/Initialize`, called 20,000 times without ruins,
creates a string list of the broken and burnt states. This carries the
fixed cost of `Join`, which is very expensive, as well as some (not
crazy, but not negligible) proc overhead.

These vars were used for effectively nothing, and have been replaced
with just using the list when necessary, which only adds an extra
millisecond of cost to update_overlays.

This was also used to automatically set `broken` and `burnt` at runtime.
However, this looks like it has gone completely unused. Adds a unit test
which adds it as a static field to the only type that cared about it,
which was abductor tiles, which is wrong anyway, but Whatever. I want to
support people making a subtype of floor tiles that are pre-broken
without it messing up stuff silently, so the test is there.

While I'm at it, renames `setup_broken_states` and `setup_burnt_states`
to remove `setup_`, since they don't really do that anymore (and never
did).

Also also, adds support for `PERFORM_ALL_TESTS` to work with multiple
focuses.

For reviewing, basically all of the changes are in floor.dm, aside from
test stuff, which is unit_test.dm.
