Fix: Life and Mana Degen doesn't affect new chainbreaker and Kaom's Spirit and apply rage buff effect correctly

[Sinured]

Fixes #4855 .
Fixes #4863 .

Description of the problem being solved:

The new Chainbreaker and Kaom's spirit rage regeneration was based on total life/mana regeneration after calculating degens. Its calculation time is now based on after calculating the recovery rate from regeneration and before any other calcuations work with LifeRegen/ManaRegen because of the UnaffectedBy mod.
Additionally, rage regeneration from these two sources didn't add the Condition:CanGainRage flag which prevented any rage buffs to apply.

Steps taken to verify a working solution:

• checked that chainbreaker and kaom's spirit apply still apply rage regen and their respective UnaffectedBy mod.
• checked that with 50 rage selected in the configuration tab dps is increased when selecting either of the two.
• checked that both ragen regen stack
• checked that the life degen and triple rage buff affect apply from Rite of Ruin
