tdf#108350: Use Carlito for DOCX import by default

In OOXML (i.e. Word since 2007), the default document font is Calibri
11 pt. If a document doesn't contain font information, we should assume
our metric-compatible equivalent Carlito to provide best layout match.

A unit test included.

An existing unit test (testN766487) was corrected to match the font
size that Word uses (11; was 12 which doesn't match Word's size).
