tdf#132599 cui offapi sw xmloff: add hyphenation-keep-type

Support XSL attribute "column" and CSS 4 attribute "spread",
stored in loext:hyphenation-keep-type, to give better control
over hyphenation-keep. E.g. spread: both parts of a hyphenated
word shall lie within a single spread, i.e. when the next page
is not visible at the same time (e.g. the next page is not a
right page of a book).

– css::style::ParaHyphenationKeep is a boolean property now,
importing hyphenation-keep = "page" as true.

– type of ParaHyphenationKeep, including the new non-ODF types
is stored in the new ParagraphProperties::ParaHyphenationKeepType.

– default value of ParaHyphenationKeepType is COLUMN for
interoperability.

– Add checkboxes to Text Flow -> Hyphenation Across in
paragraph dialog:

* Column (previously: Hyphenate across column and page)
* Page
* Spread

– enabling/disabling them follows XSL/CSS 4/loext, i.e.
possible combinations:

* No Hyphenation across
(hyphenation-keep = "page" and loext:hyphenation-keep-type = "column")

* Hyphenation across [x] Column
(hyphenation-keep = "page" and loext:hyphenation-keep-type = "page")

* Hyphenation across [x] Column [x] Page
(hyphenation-keep = "page" and loext:hyphenation-keep-type = "spread")

* Hyphenation across [x] Column [x] Page [x] Spread
(hyphenation-keep = "auto")

– Add ODF import/export

– Update DOCX import

– Add ODF unit tests

Note: recent implementation depends on widow settings: disabling widow
handling allows hyphenation across columns and pages not only in table
cells.

Note: RTF import-only, but not used bPageEnd has been renamed to bKeep.
Depending on the RTF test results, likely it will need to disable
the layout change, e.g. GetKeepType()=ParagraphHyphenationKeepType::AUTO,
if PageEnd uses obsolete hyphenation rule, i.e. shifting only the
hyphenated word to the next page, not the full line.

More information:

– COLUMN (standard XSL value, defined in
https://www.w3.org/TR/2001/REC-xsl-20011015/slice7.html#hyphenation-keep)

– SPREAD and ALWAYS (CSS 4 values of hyphenate-limit-last,
equivalent of hyphenation-keep, defined in
https://www.w3.org/TR/css-text-4/#hyphenate-line-limits).
