Game Preferences Update

[AffectedArc07]

What Does This PR Do

This PR updates the DB schema for a toggles_2 column since we are out of bitflags. It also condenses some single-bool columns into this bitflag (SQL update file will make sure existing prefs are preserved).

It also goes over the existing toggles to make it obvious what they are
Fixes #13733

And yes. This has been tested. thoroughly.

Why It's Good For The Game

We shouldnt be cut off from making more preference toggles

Code itself looks fine.
Yet I'm not 100% on making another bitflag variable on the client.
Can't we just parse the values when we load and save to the DB?

Using it this way is rather abstract compared to a boolean value

[AffectedArc07]

The reason we need an entire new variable is a BYOND limitation, not a DB limitation. We can have many more flags in the DB by increasing the int size, but the actual limit is the byond numerical limit.

Note to self: add something to backend tooling which, during testmerge start, does a hard file check for the existence of SQL/updates/X-Y.sql. If not found, auto-cancel testmerge. This safety check should forcibly prevent TMing any PR which hasn't been updated since the last SQL update PR was merged.
