Move la10c_reset into finishAndDisableStepper, which is called in both
via lcd_print_stop() and indirectly via M84, saving some space.
M84 is checked-for to determine a complete file, so it's a superior
candidate to G80 (which some people avoid due to MBL issues).
When the error count is cleared, the cumulative deltas as well as the
segment lenght which is kept inside the stepper isr need to be reset.
Introduce a helper function fsensor_reset_err_cnt to clear all the
required variables in one place which can be used in most cases
(the only exceptions being quality measument).
Introduce a new function st_reset_fsensor to also clear the segment
lenght within the isr.
The pressure state is already reset implicitly at the end of each block,
meaning an extruder switch will never have to reset the internal state
anyway.
We clear the internal backpressure in the following conditions:
- when switching to a non-LA block
- when quickStop is called
- when the scheduler is idling (losing pressure)

or DISABLE_STEPPER_DRIVER_INTERRUPT().
If this is not done, the stepper interrupt would likely overflow,
leading to a maximum 32ms delay before the stepper interrupt wakes up.
In addition, the stepper timer overflow error would be reported
by the debug builds.
