Dynamic Meta/Post effects

[Chillu1]

Describe the solution you'd like
Being able to either add, or activate/deactivate meta and post effects on modifiers. Making it, so we can do custom logic while the effect is handled at runtime

Implementation
There are two approaches:

1. Removing and adding meta/post effects inside the effect.
2. Activating and deactivating them instead.

Activation/deactivation is much better for our ram usage, amount of cloning, and generally preferred.
We'd have an int that acts like a bitset that sets the flags of which meta and post effects are active. Storing the default bitset state, and defaulting to it on ResetState.
