Update package libqt5-qtsvg from 5.12.7 to 5.15.2+kde16 (jsc#SLE-18248)

All the deleted patches come from upstream and I checked they're all included in the updated sources.
It's easy by going to https://invent.kde.org/qt/qt/qtsvg/-/commits/kde/5.15, scroll down to
"22 Jun, 2020" when the first patch "Handle empty rects" appears and then one can iterate over
the patches and the commits at the same time checking they're all there since they're mostly contiguous.

I'll reference the patches here, just in case some script checks it:
