xen/arm: arm64: Add helpers to decode and encode branch instructions

We may need to update branch instruction when patching Xen.

The code has been imported from the files arch/arm64/kernel/insn.c
and arch/arm64/include/asm/insn.h in Linux v4.6.

Note that only the necessary helpers have been imported.
