7edcb9899e Add a constructor flag to QgsCoordinateTransform to ignore impossible 
transformations, such as those which happen across different
celestial bodies

If set, the flag indicates that no user-facing warnings should be
shown and instead the transform should be short circuited

Promote QgsCoordinateTransform::TransformDirection to enum class, move to Qgis 
This enum was forcing an include of qgscoordinatetransform.h within the
widely used qgsabstractgeometry.h header, causing an absolute explosion
of includes of a bunch of very heavy header classes all across QGIS. By
removing the forced include we can avoid a ton of unwanted includes
and make wider use of forward declarations...

bd26ae1d29 Add basic support for coordinate epoch of dynamic (not plate fixed) crs 
to QgsCoordinateTransform

QgsCoordinateTransform class can perform time-dependent transformations
between a static and dynamic CRS based on either the source OR destination CRS coordinate epoch,
however dynamic CRS to dynamic CRS transformations are not currently supported.

Using the same approach as the GDAL changeset in https://github.com/OSGeo/gdal/pull/3810

b6f60f6120 Add QgsCoordinateReferenceSystem::operation() for retrieving details 
of the associated proj operation for a CRS

Allows callers to determine the projection used for CRS objects and
their details.

retrieving a complete list of all available PROJ operations

9e7e0d4bf6 Add QgsCoordinateReferenceSystem::isDynamic() 
Returns TRUE if the given proj coordinate system is a dynamic CRS.

A dynamic CRS relies on a dynamic datum, that is a datum that is no
plate-fixed.

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
