sw: stop inheriting SwSectionData::m_bProtectFlag from parent section

This is actually no longer inherited by accident since commit
2e32f4ed5af16a68c97a50806a42ffa2d10f1d7a because it replaced the
SwSectionFormat::Modify()->ModifyBroadcast()->CallSwClientNotify()->CallSwClientNotify()
with a call to GetNotifier()->Broadcast(), and apparently SwSection
is a SwClient of SwSectionFormat but not a SvtListener.

But some consider the new behaviour useful, as previously there was no
way to un-protect a section inside an outer protected section at all,
while in this way every section can have its own independent protection
flag. (The m_bEditInReadonlyFlag is not used for this purpose, as it is
only for the case when the document was loaded ReadOnly.)

So make it more explicit by removing the SwSection inheritance code.

A similar change was made for hidden flag in commit
91b0024965908c692bea40f47c58ea9d1bf8a596
