DRC: physical clearance doesn't consider text visbility

Description

Physical clearance checks report collisions even for text fields in footprints that are hidden/not visible.

e.g. this error persists if the text is hidden (right):

(rule "Fab collisions"
  (layer "F.Fab")
  (constraint physical_clearance(min 0.01mm))
  (condition "A.Type == 'Text'")
)

Applies to v9 and v9.99.

You can work around by changing the condition to A.Type == 'Text' && A.Visible

Steps to reproduce

1. Add a footprint
2. Hide the F.Fab refdes
3. Draw a colliding fab line
4. Use the DRC rule above
