TrapPlugin

class TrapPlugin extends FiberPlugin with TrapService

Mainly, this plugin implement a state-machine which handle regular traps (interrupt/exception), but also a set of special "hardware" trap used by the CPU to handle special cases as instruction retry/fences, MMU refill, ...

Also, as VexiiRiscv implements a few large CSR directly into a sharder memory (mepc, mtvec, ...), the TrapPlugin state-machine handles the hardware read/write with those CSR (durring trap, mret, ...).
