wasm strip: squashed patches from Armin + fixes

In addition to the squashed patches, this patch

* drops the global compiler defines in favour of a config header
file, for better ccache usage
* revers almost all header changes in favour for empty function
calls (just keeüs the premultiply table drop)
* some additional changes for unused function calls
* adapts more component files, so building the services.db and
the component_mao.cxx from the build still works

Currently crashs with anything different then soffice --writer.
Closing the document also crashes.
