Subject: sw, viewing OLE objects: also protect "common" embeded objects

Commit 4f9f1ac33366817df61c488a9f36b09c592ee939 (sw: allow viewing OLE
objects in protected sections, 2021-11-25) allowed launching OLE objects
in protected sections, and then made sure that changes done in "real"
OLE editors (on Windows) are discarded: both the native data and
preview.

Extend this mechanism to also handle common embedded objects (i.e. when
we load the data into an own document model, like Calc-in-Writer on
Linux): there we can simply load the data read-only, so there will be no
need to discard anything.

This requires some way to pass down the read-only flag from sw/ to
embeddedobj, implement XInitialization on OCommonEmbeddedObject to do
that.
