AGP version 7.4 deprecated the use of "package" attribute in the
manifest to specify the unique package name, it's instead been
moved to build.gradle file and set using "namespace" property.
This patch adds support of that to androiddeployqt.
Removing the "package" attribute from the default manifest would
break Qt Creator 13 and below because Qt Creator would fail to
deploy apps without such attribute in the manifest. For that reason
we'll defer removing it until a later version, for example Qt 6.10,
to allow some buffer for a Qt Creator that can handle that to be
adopted by users to reduce breakage.
[ChangeLog][Android] Add support for namespace in build.gradle instead
of the package attribute in the manifest.
