opcodes/arc: Implement style support in the disassembler

Update the ARC disassembler to supply style information to the
disassembler output. The output formatting remains unchanged.

opcodes/ChangeLog:
	* disassemble.c (disassemble_init_for_target): Set
	created_styled_output for ARC based targets.
	* arc-dis.c (find_format_from_table): Use fprintf_styled_ftype
	instead of fprintf_ftype throughout.
	(find_format): Likewise.
	(print_flags): Likewise.
	(print_insn_arc): Likewise.
