feat(QGCCorePlugin): allow hiding initial setup sections

[rubenp02]

Description

Makes it possible for custom builds to hide either the Vehicle Preferences or Measurement Units section from the initial setup prompt. Hiding both sections omits the prompt. This restores the control available before the two prompts were merged.

In addition to this, this commit fixes a bug where the initial setup prompt showed an empty Vehicle Preferences section when only one firmware and one vehicle type are supported. Its heading and description now hide with its controls. The visibility logic that drives this now lives in QGCCorePlugin instead of QML.
