Readability vs. optimization 😃

In the conversion of a vtkUnstructuredGrid replace the 5*(nr of elements) GetCell() calls with vtk's provided function. The 5*(nr of elements) GetCell() calls make around 50% of total instruction spent in convertUnstructuredGrid(). For current groundwater flow simulation without the linear solver call it makes around 1/6 of total instructions.
This saves 16% of instructions in the GroundwaterFlow::init() code due to faster access in the multi-index table.
Replace two-pass method in createMeshElemPropertiesFromASCRaster untility.
In particular use shift operation.
if(TARGET ..) only works if the target is defined before this statement which was not the case. The OGS_BUILD_GUI variable is always defined.

ctest -E diffcommand needs around 10% less time.The latter changes are touching a createMeshPropertiesFromASCRaster,
which I could not test. It seems the code is not compiling at all. Probably I miss some special flags for cmake.(Thanks to Lars for fixing compilation)Please test this.
Also the performance of VtkTextureOnSurfaceFilter should increase significantly. How can one check this? (and more important, that my changes do not break anything?) (:white_check_mark: Thanks Lars!)
