CircularDeque: Correctly pass args to enqueue

Problem:
- Using regular functions rather than function templates results in
  the arguments not being deduced. This then requires the same
  function to be written multiple times and for `move` to be used
  rather than `forward`.

Solution:
- Collapse multiple function overloads to a single function template
  with a deduced argument. This allows the argument to be a forwarding
  reference and bind to either an l-value or r-value and forward the
  value.
