Clear TLO reference on homing cannot be handled by plugins

[rcp1]

Hi,

if I would want to takeover the handling of TLO / TLR in a plugin, I can't clear their state on homing in the moment since the current iface namely tc_clear_tlo_reference is hard-coded in the homing cycle:

https://github.com/grblHAL/core/blob/06f442643a115ab3acd6722b4afc1fcee8d9d7be/motion_control.c#L833

But the tc_clear_tlo_reference does nothing if the tool change is not handled by / disabled for tool_change.c.

Would it be possible to add a grbl. function for this, so I am able to inject plugin code here or just always reset TLO/TLR on homing?

I wonder if it will be better to hook tc_clear_tlo_reference into the grbl.home_machine handler chain and only do so if the core tool change code is active? And move tc_clear_tlo_reference to system.c and remove the mode check so that it can be reset by your code by also hooking it into the grbl.home_machine chain?

I am going to change the signature of grbl.on_homing_complete (add the cycle mask) and move tc_clear_tlo_reference to system.c as system_clear_tlo_reference (without the mode check).

Sounds good, one could even hard-code system_clear_tlo_reference to always execute in homing of the tool change axis.
