Android: Support for separate landscape/portrait splash screens

To get appropriate aspect ratios for the splash screen, you usually
need separate drawables for the portrait and landscape versions.

We support this by adding two new meta data entries that can be used.
If they are not available, we will fall back to the generic one,
so we are still compatible with existing AndroidManifest.xmls.

[ChangeLog][Android] Added entries in the AndroidManifest.xml for
specific portrait and landscape splash screens. If one is present
for the current orientation, it will be preferred over the generic
one.

Task-number: QTBUG-74029
