Rover support for FRAME_CLASS/FRAME_TYPE

Rework ArduPilot Airfame setup page

Bug noted in #3465

During tests, if the airframe was configured to be an 'X' type
we showed just 'X' on the airframe type. It's correct but a
single letter - specially an X - made users think that it was
a error code, not the airframe name. So, because of that, also
show the vehicle type - a wrong value, but elucidative for users.

I removed some needed headers from a top level file which then causes a
ripple effect downstream

Strings can be expensive to create, all the issues with allocation,
copy of the char members, conversion to UTF-16. QStringLiteral creates
one in compile time.

This commit introduces the APM Airframe configuration. The interface
is the same as the PX4 one, but the way we deal with the uas is a bit different

Since the APM stack doesn't provide a xml with airframe definitions a
new one was created by hand with only the values that we need, wich will
trigger a download of the parameters file from the mavlink github

Now it correctly handles the FRAME variable and it's faster
regarding the download of the parameters for each type of Frame.

Only show Airframes for ArduCopter, not for ArduRover nor ArduPlane
