WIP: Implement BIP9 and get BIP113 to be ready to be deployed with it as an example #7566

   An implementation of BIP9.

   Unnecessary but good-to-have dependencies:

   - [ ] Interface for chain.o #7563 - [ ] BIP113 ready for trivial deployment #7565

   TODO:

   • GetMinerNextVersion()
   • warnings when undefined (for you) rule changes are locked_in/activated according to bip9 rules.
   • Unittests

   EDIT: Use BIP68 + BIP112 as example deployment instead of BIP113.

14. BIP9: Introduce consensus/interfaces.h with CVersionBitsCacheInterface

    This file is intended to be compatible with a C API, thus uses simple
    structs and function pointers instead of C++ classes and methods.
