Move some uncontroversial char-folding pairs from test data to default values

* lisp/char-fold.el (char-fold--default-include)
(char-fold--default-exclude): Add some default values.

* test/lisp/char-fold-tests.el (char-fold--test-without-customization)
(char-fold--test-with-customization): Move some test data to
default values.  Add more data for tests to pass.   (Bug#35689)
