configure: add option to allow building without evr support
Because of issue QTBUG-53019, the performance of an application playing a
video on windows is sometimes just a few fps. The issue seems to
be related to EVR on some hardware, and appeared in commit c739752.
This patch allows building the qtmultimedia module without EVR.
Task-number: QTBUG-53019
