Protect End-Users from themselves: Advanced Motion Control settings

[futurexdesign]

For development/testing purposes, there is an advanced settings menu that lets the user adjust things like the GlobalScaler and IRun / IHold settings of TMC5160. These are surfaced to allow tuning of the motion controller to find the best settings for the stepper motor while under normal load. These directly impact the amount of current the motion controller will use when running the stepper motor. As such, it is completely possible to set these to a level that may damage the stepper motor, or the stepper control board.

tcMenu supports pin protection of menu items. We should probably add a pin to protect these menus from being "easily" accessed.

An alternate option also may be to just use one of the GPIO available on the Expansion header as a switch for showing/hiding the advanced menu in the UI. That way one would need to physically interact with the board, grounding a pin on the expansion header to even get the menu to appear?
