Description
-----------

* Computes the element-wise absolute value of each element
  in the operand x and stores the result in y.

* ``T1`` and ``T2`` must be one-dimensional containers with compatible scalar types:

  * an Eigen vector

  * a Kokkos rank-1 view

  * a Tpetra vector

  * a Tpetra block vector

  * a Pressio expression, i.e. ``pressio::diag``, ``pressio::span``, ``pressio::subspan``, based on Eigen or Kokkos container
