class BtbPlugin extends FiberPlugin with FetchWordPrediction with InitService

Implement the Branch Target Buffer in the fetch stages, aswell as the Return Address Stack. See https://spinalhdl.github.io/VexiiRiscv-RTD/master/VexiiRiscv/BranchPrediction/index.html#btbplugin for more doc. in particular to understand the chunk topology.
