Replace "it.dmg.value" with "it.notZero" for multiple damage modifiers applied before W/R, plus some other fixes in those code sections

[starg09]

When finished, should fix some issues with cards such as "Darkness Energy vs Metal Energy" in wizards formats, or "Professor Kukui vs Pressure/Intimidating_Fang" in recent formats.

Counts as a mass replacement, so leaving a checklist for looked-around gens:

• [x] Gen 1 [Groovy reimplementations]
• [x] Gen 2
• [x] Gen 3 [Sets in Groovy implementation]
• [x] Gen 4 [What's implemented here, DP-CL]
• [ ] Gen 5 [Cards using Groovy implementation]
• [ ] Gen 6 [Cards using Groovy implementation]
• [x] Gen 7
• [x] Gen 8

Sets not entirely fixable this way:

• Gen 1 [Legacy implementation]
• Gen 3 [Sets in Legacy implementation, RS-HL]
• Gen 5 [Effects that may use legacy code]
• Gen 6 [Effects that may use legacy code]

Check order of operations between Metal Energy (Special) and Darkness Energy (Special), in wizards era formats. Also, all damage boosters vs damage reducers in general.

Hi @flagrama could you review this one please?

[starg09]

Turning into draft as there's now many gen 4 sets implemented, which may need updates in this regard.
