Mandate all probe cycles ignore feed overrides.

- For repeatability reasons, all G38.x probe cycles ignore feed rate
overrides and move at their programmed speed.

- The mandate can be removed with a new config.h option.

- Updated the documentation to reflect the change.

+Subject: Resolved parking accessory handling issue.

+- Yikes. Totally borked the last parking “fix”. Testing shows that all

+was caused by not accounting for the planner re-factoring correctly in
+the parking code.
