tests: port to new QMutableEventPoint static API

This code didn't actually use QMutableEventPoint::from(), so didn't
run into the UB that from() depended on, but it's in the way of making
QMutableEventPoint a befriendable namespace instead of a public
subclass of QEventPoint.

Replaced the QMutableEventPoint ctor that takes a timestamp, and
therefore isn't compatible with the ctors on QEventPoint, with a
static function that returns QEventPoint instead.

Port QList initialization to braced-initialization as a drive-by.

Task-number: QTBUG-99615
Pick-to: 6.3
