tdf#95425 follow-up: enable "Source format" checkbox of data label

settings after file opening, if its value is true in the opened
ODF or OOXML document, instead of always showing disabled state.

Testing notes: double click on a data label during chart editing
of unit test document testAreaChartNumberFormat.docx of
commit e57d90cd4e51a1353eafc87bb29cfe6076704a7c
(tdf#129173 tdf#129175 Fix number format of data labels)
to see the Data Labels for Data Series... window. On the page
"Data Labels...", click on the Number format... button to see
the enabled checkbox "Source format" (that was disabled
previously).
