Start with instantiation of FETools::get_fe_from_name()
Existing testbits/get_fe_from_name passes
Modified all get_name functions to include the spacedim parameter.
Added one test for codimension one finite element generation from names.
Reintroduce get_fe_from_name<dim>() with one template parameter as deprecated
New function get_fe_by_name<dim,spacedim>()

Fix memory_consumption_01 for icc

The comparison file for compiler=Intel=yes was just invalid. Current icc
does not miscompile the test in release mode anymore. So remove all special
comparison files.

Move create_union_triangulation() and extract_boundary_mesh().

These functions were previously in GridTools, but conceptually they create
meshes and so should be in GridGenerator. Move them there but leave the
old functions in GridTools with a note that they are now deprecated.

Also structure the documentation of the functions in GridGenerator better.

CMake: Remove non-functional code

This actually never worked...
CMake: Remove all "help" targets

It turns out that CMAKE_PROPERTY is too buggy to be useful. We cannot
set property CMP0037 to the old behavior in order to define a custom "help"
target in a macro without a warning. o_O
