autotest: add frame-aware Location class

Browse Source

mavutil.location has no altitude frame field; its alt is AMSL only by
convention and the suite routinely stuffs relative-to-home and terrain
altitudes into it, leading to silent frame-mixing bugs.

Add a Location class mirroring AP_Common's Location: meters altitude
tagged with an AltFrame (ABSOLUTE/ABOVE_HOME/ABOVE_ORIGIN/
ABOVE_TERRAIN). It deliberately has no alt attribute. Altitude is
only reachable via get_alt_m(frame), and asking in the wrong frame is
an error, not a conversion: code that assumes a frame fails loudly
instead of silently misreading the altitude. Converting is its own
explicit step, TestSuite.change_alt_frame(), which polls home, origin
or terrain data from the vehicle as required.
