Various code clean ups. (#11901)

No functional changes.

Clean ups:

- Rewrap some comments that were poorly wrapped due to past code reformatting.
- Use GridBagConstraintsBuilder in BattleCalculatorPanel to make the code much more concise
- Switch some countMatches() calls to noneMatch() and anyMatch().
- Remove some unnecessary logic prior to calling getMaxUnitsToBePlacedFrom(), since getMaxUnitsToBePlacedFrom() does that logic already.
