Moved the generated apply* methods from StyleBuilderFunctions.cpp
to the property classes for 'auto' properties which share a non
custom template:
- clip
- column-count
- column-gap
- column-width
- z-index

Also fixed includes so that headers required for apply* functions
are only included when those functions are implemented, not
when they are to be declared only.

Note that this patch creates duplicated logic in
make_css_property_headers.py and make_style_builder.py.
Since it is planned to remove style builder as part of this project
I have not bothered factoring this logic out.
