bfb1dd7672 [api] Add QgsCoordinateReferenceSystem::factor()
Calculate various cartographic properties, such as scale factors,
angular distortion and meridian convergence for the CRS at a
given geodetic point (in geographic coordinates).

Depending on the underlying projection values will be calculated
either numerically (default) or analytically. The function also
calculates the partial derivatives of the given coordinate.

Internally uses the proj library proj_factors API to calculate the factors.

Fixes #41952
