Adding signals for width and turn diameter

[erikbosch]

This is inspired by some signals in Android VHAL with no corresponding signals in VSS; In INFO_EXTERIOR_DIMENSIONS there are fields for width with and without mirrors and also turn diameter.

We could possibly make use of 3 widths

• Excluding mirrors
• With mirrors folded
• With mirrors in normal position

Here we have SAE definitions we could use. We already have a Width signal, but that signal does not specify how width shall be measured. It is suggested to mark that signal as deprecated (for VSS 4.1) and thus with our present deprecation process remove it for VSS 5.0

For turn diameter two measurement can be used, wall-to-wall and curb-to-curb. The SAE standard only give a definition for wall-to-wall:

"Diameter of the minimum cylindrical envelope in which the
vehicle can drive a circle with the front wheels at maximum
lock (between walls). If different between left and right turn,
the larger one is reported".

That is the diameter proposed in this PR

Meeting notes:

• Please review
• Nick: Better to duplicate signal instead of changing meaning, like WidthExcludingMirrors, Keep Width, mark obsolete

[SebastianSchildt]

I don't think in VSS we want both turning radii. More practical seems to have "wall-to-wall", see also Wikipedia, just calling that TuringDiameter, and write in description the specific definition used
