tdf#146756 pie chart2 import: use manualLayout Width for pie chart labels

... and use a compatible 1/5 width if not specified.

This patch depends on the previous oox patch
(commit 301e27cbebf7d6e4c9b82290d7cd555c43f0c999)
which actually reads the width into the model.

Fixes a 7.2 regression from

tdf#138777 pie chart: improve long data label width

and is basically a re-write of 7.1's

tdf#134978 Chart OOXML Import: fix pie chart label custom position

This is very risky, but then ANYTHING changing chart2 is risky.
There were a lot of changes made in 7.1,
and they all invited regressions.
However, our chart implementation is not in a good state,
and certainly is not very interoperable,
so it is worth taking the risk.

Anything dealing with manualLayout at this point
should have originated as a pptx,
so forcing a compatible max width should be fairly safe.

It probably isn't actually all that risky after all.

largely copied code from

tdf#48436 Chart: add CustomLabelPosition UNO API property

Fortunately this all goes away after a round-trip
since custom label placement is lost on export to OOXML,
and that really helps to reduce the risk.
