Add Firmware Features extension

This extension is meant to provide a way for supervisor-mode software to

firmware. Two new functions are added to get and set theses feature with
specific values. This first FWFT extension version documents the
following features:
- MISALIGNED_EXC_DELEG: Delegate misaligned access exception
- SOFTWARE_CHECK_EXC_DELEG: Delegate software check exception for
  supervisor-mode[1]
- LANDING_PAD: Control Landing Pad for supervisor-mode[1]
- SHADOW_STACK: Control Shadow Stack for supervisor-mode [1]
- DOUBLE_TRAP: Control Double Trap support for supervisor-mode [2]
- PTE_AD_HW_UPDATING: Control hardware updating of PTE A/D bits

An openSBI implementation is visible at [3] as well a kvm-unit-tests
with MISALIGNED_EXC_DELEG testing at [4].
