add_test: Allow special characters in test name (w/ policy CMP0110)

Restore the change from commit f84af8e270 (add_test: Allow special
characters in test name, 2020-05-16, v3.18.0-rc1~142^2) that had to be
reverted by commit f84af8e270 (add_test: Allow special characters in
test name, 2020-05-16, v3.18.0-rc1~142^2) for compatibility.

Add policy CMP0110 to make the change in a compatible way.
Also, support even more characters than before by generating the
test scripts using bracket arguments around the test names.

Fixes: #19391
