[MIRROR] Add: 2 Quirks Configs (#26206)

* Add: 2 Quirks Configs (#81033)

This PR adds two new config options for quirks:
- *Flag* `DISABLE_QUIRK_POINTS`
  - When enabled, disables quirk points balancing.
- When enabled, players can select positive quirks without first
selecting negative ones.
- When enabled, the quirk points balance visually hides itself on the
Quirks page.
- *Number* `MAX_POSITIVE_QUIRKS`
- Limits the maximum quantity of positive quirks which players can
select using the Character Preferences page.
  - I ported this from the old `MAX_QUIRKS` define.
- When set to `0`, players won't be able to select any positive quirks,
and they won't appear on the Quirks page.
- When set to `-1`, players will be able to select any quantity of
positive quirks.
  - When commented-out or undefined, the default is `6`.
- When set to `0` or `-1`, the positive quirk balance visually hides
itself on the Quirks page.

There is some downstream repositories asking for the quirks system to be
configurable. Additionally, I always find myself tweaking these values
on my own private servers and I thought it would be nice to share my
edits. Usually I was simply commenting-out sections of this code in
order to get the same result, so it helps to have an official way to
disable quirk points.

🆑 A.C.M.O.
config: Added two new config flags for quirks, DISABLE_QUIRK_POINTS and
MAX_POSITIVE_QUIRKS.

* Oh come on
