writerfilter: implement formprot

The document properly opens with all sections protected because
document protection (forms view) is enabled. However, when that
setting was toggled off, all sections wrongly became unprotected,
and remained unprotected when round-tripped
(including in Word - so loss of configuration).

Word does protection differently. It opens up in a forms only mode,
but upon enabling editing mode, the individual sections can
still be protected. Only when global enforcement is disabled
do all sections become editable.

So, if global enforcement is enabled, map the section protection to
LO native protection. On startup, the sections will all be protected
because of the global compatibility flag. If the flag is turned
off, then you enter a similar mode to Word's "Edit document" where
the sections are still protected. In LO, *each* section's protection
must be turned off individually to fully disable enforcement.

This patch keeps the same three-step process to fully edit the
entire document, but the meanings take on a different form.
"Compatability: Protect Form" changes from "enforcement" to
"edit document" in concept. BTW, that matches how export works,
where PROTECT_FORM is auto-enabled if any sections are protected.

Section protection in LO can be disabled through
Format - Sections - Write Protection.

Patch initially developed to support tdf#120499.
It depends on an earlier commit in order to round-trip.
