ENH: Release the GIL in einsum() special-cased loops (#9246)
* ENH: Release the GIL in einsum() special-cased loops
This does not only allow parallelization but also fixes issues where a background
IO loop would suffer long wait times due to a large concurrent einsum() in another
thread.
* Use NPY_BEGIN_THREADS_THRESHOLDED
* Add release notes entry
