tdf#142417: Improve convertfilters.py and add API Names column

This commit involves two parts:
1. Improved the convertfilters.py helper script to make sure
the generated convertfilters.xhp file is complete, accurate
and containing no duplicated entries, and also add codes
to also generate API Names column, as discussed in tdf#142417.
Importantly, the code is modified to generate fixed IDs,
rather than the previously random IDs or sequential IDs which
may make the PO translation strings to show fuzzy when the
file is re-generated.
2. This helper script is run and the convertfilters.xhp is
updated.
3. The default css is modified to better display the page.
There is no need to set overflow=auto for the DisplayArea,
otherwise the scrollbar goes to the bottom of that area which
is not visible. Also added a css class to display smaller
fonts for the table.
