tdf#165803 use COL_WHITE for DOCCOLOR for both light and dark modes HEADmaster

LibreOffice since 1995 has used light as the default background color
for slides and documents. 'LibreOffice Themes' broke this behaviour as
it depends on the hardcoded color values for the document colors.

if the desktop environment is in dark mode, a dark document color is
used. this causes issues for the slides created pre themes as they
were created with white slide background. issues like black text on
black background.

this is also concerning because DOCCOLOR is not saved with the document,
so if someone creates slides/documents with DOCCOLOR in mind, they would
be disappointed to see the difference.

so the simplest solution to this problem would be to use white color for
both light and dark modes.

since we would be using COL_WHITE for DOCCOLOR after this patch, it would
be best change CALCGRID as well, to use a lighter shade of grey in dark
mode (which would match the document color changes)

changing DOCCOLOR value to COL_WHITE for dark mode broke a sd_tiledrendering
test it was using the DOCCOLOR to check if dark or light theme is being
used. commented that test out for now (just for this patch).

reworking themes ui and implementation details to simplify the feature.
