Avoid multiple connects in SKIPIF sections (GH-15470)

Besides checking for the ability to connect to the MySQL server, some
tests require additional checks (e.g. to be able to check for the
server's version) as skip condition. There is no need, though, to
connect twice; instead we introduce `mysqli_connect_or_skip()` in
test_helpers.inc, which `die()`s with an appropriate error message, if
the connection can't be established, or returns the connection link
otherwise.

Use --EXTENSIONS-- section for newly added tests

As of PHP 8.1.0, the `--EXTENSIONS-- section is properly supported, and
CIs may make use of that (our AppVeyor CI does). Thus it is important
to list required extensions there, since otherwise they may not be
loaded, causing the test to be skipped, or worse, to be borked.
