patch 9.2.0574: tests: missing test for v9.2.0572

Problem: tests: missing test for v9.2.0572 (the patch accidentally
included some additional unwanted changes from https://github.com/vim/vim/issues/20372)
(thinca)
Solution: Add additional test for delfunc
(thinca)

Patch 9.2.0572 fixed ":call d.key()" and ":delfunction d.key" failing
with E1017 in Vim9 script, but only the :call form was covered by a
regression test. Add Test_delfunction_dict_funcref to exercise both
"delfunction d.key" and "delfunction d['k2']".

closes: #20372
