1.x-1.8.0

Release 1.8.0 of Devel module brings the Backdrop version a little more inline with the Drupal version and fixes several bugs. Added compatibility with PHP 7.4. See the 1.8.0 milestone for a list of issues fixed.

This version removes the XHProf integration entirely due to the complete end of support for XHProf and the difficulty of getting the replacement extension (Tideways) working with the old XHProf library.
