Add state/framework/etc. conditional compile flags

This adds conditional compilation for the following features, in
addition to the voice conditional compilation flag:

- extras (message builder)
- framework
- methods
- state

These 4 are enabled _by default_, while the `voice` feature flag is
disabled.

Disabling the state will allow incredibly low-memory bots.
