[FEATURE][processing] New algorithm "Geodesic line split at antimerid…

…ian" Ports the similar algorithm from the shape tools plugin to c++, and utilises built in QgsDistanceArea ellipsoidal calculations to split the lines. This algorithm splits a line into multiple geodesic segments, whenever the line crosses the antimeridian (±180 degrees longitude) Splitting at the antimeridian helps the visual display of the lines in some projections. The returned geometry will always be a multi-part geometry. Whenever line segments in the input geometry cross the antimeridian, they will be split into two segments, with the latitude of the breakpoint being determined using a geodesic line connecting the points either side of this segment. The current project ellipsoid setting will be used when calculating this breakpoint. If the input geometry contains M or Z values, these will be linearly interpolated for the new vertices created at the antimeridian. Supports in-place edit mode also.
