Improved Threshold Scan, Touch and other small fixes

Description

Brings CARTOGRAPHER_THRESHOLD_SCAN into line with CARTOGRAPHER_TOUCH

Based on KrauTech-Nightly with improvements.
Maintains same command params from previous iteration for backwards compatibility.

Checklist

The following relevant macros have been tested:

• CARTOGRAPHER_CALIBRATE
• PROBE
• PROBE_ACCURACY
• CARTOGRAPHER_THRESHOLD_SCAN
• CARTOGRAPHER_TOUCH CALIBRATE=1
• CARTOGRAPHER_TOUCH
• CARTOGRAPHER_TOUCH METHOD=manual
• BED_MESH_CALIBRATE

Tested _THRESHOLD_SCAN and _TOUCH on my printer, worked fine.
Found threshold of 1750 and touched with one retry.

I'm not happy enough with this yet. It clearly has issues.

Either 1. Its not outputting text about the other Qualify attempts or 2. Its moving onto the next threshold instead of doing all 5 qualify attempts and checking the results.

cartographer-klipper/scanner.py

Lines 792 to 808 in 2dfe5f0

	consistent_results = True
	for attempt in range(repeat_attempts):
	repeat_result = self.start_threshold_scan(
	gcmd, touch_settings, verbose
	)
	if not repeat_result["success"] or (
	repeat_result["standard_deviation"]
	> max_acceptable_std_dev
	):
	gcmd.respond_info(
	f"Qualify attempt {attempt + 1} failed for threshold {current_threshold}"
	)
	consistent_results = False
	break
	gcmd.respond_info(
	f"Qualify attempt {attempt + 1} successful with std dev: {repeat_result['standard_deviation']:.5f}"
	)

Potentially in here.

It looks good to me. Just had that one comment I would think about :)
