target/xtensa: extract test for cpdisabled exception

- add XtensaOpcodeOps::coprocessor with bitmask of coprocessors used by
  the instruction;
- replace coprocessor id parameter of gen_check_cpenable with the
  bitmask of used coprocessors;
- collect coprocessor IDs used by an instruction in the disassembly
  loop;
- put test for coprocessor disabled exception after the alloca test;
