fdo#67957: Font name reported in AXFont always Times New Roman

This is a partial fix. Now VoiceOver does report changes in font faces
but it works correctly only when the paragraph text style has font
"Times New Roman". If it has not, then parts of the text with
"Times New Roman" have not change in font reported, but parts with
font different both from the paragraph style font and "Times New Roman"
do have font change reported.

In other words, the default font for paragraph is still "Times New Roman"
in accessibility even though sometimes it's not true.

This also fixes font size being reported only when bold or italic is set,
and has more robustness for handling mixed bold/italic when at least one
of them is set in the paragraph style as well.
