Allow all hierarchical path segments to be ['...'] quoted

...and not just set elements.  <https://gerrit.libreoffice.org/c/core/+/151660>
"tdf#104005 Don't allow changing finalized properties" found that some existing
property names include "/", which makes them unusable with e.g.
getPropertyByHierarchicalName.

The most obvious solution is to allow ['...'] quoting (without a leading
template name, though) for all kinds of hierarchical path segments.  (In theory,
that would cause backwards incompatibility, as e.g. a property named ['foo']
could no longer be referenced by a ['foo'] path segment (it would need to be
referenced by a ['[&apos;foo&apos;]'] path segment instead).  But in practice,
that path segment ['foo'] would have been rejected in the past anyway, as it did
not reference a set element.)

To make this work, the meaning of the setElement out-parameter of
configmgr::Data::parseSegment is changed to only be true if the segment uses
['...'] notation including a leading (non-empty) template name.

What this change does not (yet) address is writing out such quoted (group or
set) names in the hierarchical paths written out in configmgr::writeModFile,
where necessary.  (It never writes out names of properties as parts of
hierarchical names, so this wouldn't be an issue for the existing problematic
properties containing "/" in their names, anyway.)
