[ARM64] Make BufferDisassembler print the instruction encoding

[ARM64] Make BufferDisassembler print the instruction encoding

This patch changes the disassembly output for ARM64 when tracing
compiled code. We used to omit printing the encoding as opposed to what
ARM and X64 do. The new turbolizer tool assumes the encoding is printed
and gets confused otherwise.

This could have been fixed in the tool instead but making disassembly
output consistent across architecture seems like a better solution.
