tdf#95615 android: Don't offer "Save" after opening templatedistro/lhm/libreoffice-7-1+backports

When the input document in Android Viewer is a template,
a new doc is created and a plain '.uno:Save'
(which 'LibreOfficeMainActivity#saveDocument' triggers when the
"Save" menu entry is selected) will therefore fail.
A proper URI to save to (rather than overwriting the
template itself) is only known after a "Save As" anyway,
so don't set the 'mDocument' member until then, which leads to
the "Save" menu entry becoming disabled, just as is the
case when explicitly choosing to create a new document in
the start activity.

For now, the check whether the document is a template
checks whether the MIME type detected for the URI
ends with "template", which is the case for ODF and
OOXML types (like
"application/vnd.oasis.opendocument.text-template" or
"application/vnd.openxmlformats-officedocument.wordprocessingml.template").
This can be refined further as needed, e.g. by explicitly
adding more MIME types to check.

(Editing the actual template instead of creating a new doc
from it would be a different use case that remains
unsupported also with this change in place.)
