Doc: Add qt6-changes.qdoc to Qt Multimedia

This is part of the porting documentation structure in Qt 6, and
all modules part of Qt 6 should have such a document. Add skeleton
doc so that the dev team can extend with real content, and to
ensure that automated lists contain correct entries, etc.

+    \brief Migrate Qt Multimedia to Qt 6.
+
+    Qt 6 is a result of the conscious effort to make the framework more
+    efficient and easy to use.
+
+    We try to maintain binary and source compatibility for all the public
+    APIs in each release. But some changes were inevitable in an effort to
+    make Qt a better framework.
+
+    In this topic we summarize those changes in Qt Multimedia, and provide guidance
+    to handle them.
