The build takes too long because of this and nobody uses it anyway. CUDA
does not support long double in device code at all.

DistributedNDArray: added methods getLocalIndexer, getLocalView, getConstLocalView, getStorageIndex and getData

This is necessary for local indexing of DistributedNDArray.

It works for any value, device and index types, but the permutations of
both arrays must be the same and both arrays have to be contiguous.

- fixed executors for operations: use inverse permutation when calling
  the wrapped lambda function
- custom internal region can be specified with custom begins/ends
  multiindices

NDArray: moved SizesHolderStaticSizePrinter and SizesHolderSizePrinter into the implementation namespace

Fixed expression templates

Brief summary:

- fixed `DistributedExpressionTemplates`
- many fixes and simplifications in `ExpressionTemplates` and `StaticExpressionTemplates`
- extended tests (unified for `VectorExpressions`, `VectorViewExpressions`, `StaticVectorExpressions`, `DistributedVectorExpressions`, `DistributedVectorViewExpressions`)
- functions `maxNorm`, `l1Norm` and `l2Norm` - convenient aliases for `max(abs(...))`, `lpNorm(..., 1)` and `lpNorm(..., 2)`
- a `cast` function which makes something like this possible:
  `float s = TNL::sum(cast<float>(vector))`, where vector elements may be `int`, `double`, etc.
- fixed result types in expression templates and vertical operations
- removed `addVector`, `addVectors`, `addElement`, `scalarProduct` and `sum` methods from all vector types
