opcodes/loongarch: implement style support in the disassembler

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

opcodes/ChangeLog:

	* disassemble.c: Mark LoongArch as created_styled_output=true.
	* loongarch-dis.c (dis_one_arg): Use fprintf_styled_func
	throughout with proper styles.
