The current z_hop support did not work correctly with common slicers
that change Z height between retract and unretract, and it did not

Support retrying Z_TILT_ADJUST a configurable number of times
to a configurable tolerance both in the config or as parameters.
- By default keeps original behavior of no retries.
- Adds parameters RETRIES and RETRY_TOLERANCE to QUAD_GANTRY_LEVEL gcode.
- adds config options retries and retry_tolerance to uad_gantry_level]
- issues an error if we are getting worse intead of approaching tolerance
- issues an error if retries were requested but we did not reach the tolerance
in the specified number of retries
the minimum change should be a single z step for those
probing 2 points for 2 stepper motors and 3 for 3 stepper motors.
at one point it was suggested to use the amount of z adjustment instead of the
range of the probed points as a trigger for retry. I've chosen not to do this.
using z adustment in these cases means the minimum unit of change is related to
the angle created by the probed points and the distance to stepper motor and
can be more than a couple steps which is rather unintuitive.
for the case when someone is using more probed points than z steppers the
probed points range will have some fixed minimum value that can't be reduced
which is also unintuitive but that case should idealy be the rarer case, and
the user can learn to set a higher tolerance that matches their probing setup.

SET_SERVO SERVO=config_name [ANGLE=] [ENABLE=<0|1>]

G4 P200 ; wait 200ms
SET_SERVO SERVO=touch ENABLE=0 ; disable servo
