Refactor lighting items that use fuel (#72146)

## About The Pull Request
Fixes #71826

This does the following:
- Makes candles a subtype of flare
- Fixes candles having lighting inconsistencies
- Fixes burning items (welder, candles, flares, etc.) not causing
ignition effects when held in hand
- Adds burnt flares and melted candles to maint loot and trash spawners
- Add match lighting sound when candles are lit
- Add time defines for fuel amounts and rounded them (ex. instead of
32.3333 minutes, it's now 35 minutes)
- Light sources that burn will now spawn a trash item once fuel is spent
- Light sources that burn now have a welder hitsound
- Light sources that burn can now be extinguished by a fire extinguisher
(except flares)
- Light sources that burn can now be used to ignite another object on
fire (ex. a lit candle can be used to light a cigarette)
- Light sources that burn and are lit now do `BURN` damage while
attacking

## Why It's Good For The Game
Code is more cleaner and consistent.  Also fixes some bugs.
