[Call-for-Review][Calc] Bug 121215: Font name Arial in XLS is changed to Arial1 when save as .ods

[Tan Li]

Hi All,
    I have a patch for issue 121215, and could you help review?
https://issues.apache.org/ooo/show_bug.cgi?id=121215

Root cause:
Font pitch is set PITCH_DONTKNOW for all FontFamily while construct font
item. While some FontFamily has known pitch type. It will treat Arial with
PITCH_DONTKNOW as new font from previou Arial font in document.

Solution:
Set corresponding font pitch for FontFamily according to official
literature to avoid mistake one font as two.

Thanks!

Best Regards,
Tan Li
