Support Passing Chips as a Parameter

[falo2k]

Describe the feature or hardware support you'd like

Would it be possible to add a CHIPS parameter as with TEST_RESONANCES to select the chip we want to use where more are defined? When using something like Danger Klipper's optional mcu for nozzle probes, you can't have the optional mcu defined in the accel_chip attribute of resonance_tester (as it sometimes doesn't exist yet), but you can pass the defined chip to TEST_RESONANCES using CHIP=. It would also be handy even for fixed mount sensors, when you want to take readings from different positions and compare.
