Cleanup `makeBasis()` mechanism

Cleanup makeBasis() mechanism. This MR is on top of !91 (merged).

• Rename *NodeFactorsBuilder/*FactoryTag to *PreBasisFactory
• Rename build() to makePreBasis()
• Make makePreBasis() const
• Make implementation of BasisBuilder::composite() more readable.
• Fix BasisBuilder::composite() and BasisBuilder::power(). Both did not work with stateful ChildPreBasisFactories before. This is now fixed.
• Hide internal members of PreBasisFactories
• Use return type deduction for all PreBasisFactory creation helpers. This makes the code much more readable and also hides the concrete Imp::* return type from the use.
• Add utility applyPartial() which is like std::apply but allows to select the tuple entries to be used as arguments. (This should maybe go to dune-common).

This is what you need to do to update your code:

• If you only use the makeBasis() mechanism this will work as before.
• If you explicitly constructed the *Builder classes in your code, you must follow the renaming.
• If you explicitly used the build() methods, you have to change this to makePreBasis()
• If you implemented your own FactoryTag/NodeFactoryBuilder/PreBasisFactory to hook into the makeBasis() mechanism, then you have to rename build() to makePreBasis().
