Move commonly used API systems to a plugin based system

Create a class that implements IBloodMagicPlugin and annotate it with
`@BloodMagicPlugin`. The `register` method will be called during init.

Currently implemented systems:
- Blacklisting
  - Teleposer
  - Teleposer (entity)
  - Transposition
  - Well of Suffering
  - Green Grove
- Setting sacrificial values
- Adding altar components
