android: Offer 'Save As' in readonly mode

Provide the "Save As..." menu entry in Android
Viewer also if read-only mode is used, either
because the experimental editing mode is disabled
or there is no write access to the document.

This way, a copy of the original document
can be saved elsewhere.

In case experimental mode is enabled, editing
is allowed after saving the document.

Call 'ToolbarController#setEditMode' in
'ToolbarController#switchToEditMode' right away instead
of posting it to the main handler in a Runnable along
with the other commands (that change the UI), so the new state
is already taken into account in
'LibreOfficeMainActivity#onResume' and the toolbar
isn't switched back to view mode there right away.
