[Code Reorganization] load_two_bytes_from_at_bcp -> get_2_byte_integer_at_bcp
remove useless MacroAssembler::store_two_byts_to_at_bcp
change MacroAssembler::load_two_bytes_from_at_bcp to InterpreterMacroAssembler::get_2_byte_integer_at_bcp
change MacroAssembler::get_4_byte_integer_at_bcp to InterpreterMacroAssembler::get_4_byte_integer_at_bcp
