Make the caret visible in the text layer in caret browsing mode

Browse source 
In order to do that we must change the text layer opacity to 1 but
it has several implications:
 - the selection color must have an alpha component,
 - the background color of the span used for highlighted words
   must have an alpha component either, but now the opacity is 1
   we can use some backdrop-filters in HCM making the highlighted
   words more visible.
 - fix a regression caused by #17196: the css variable --hcm-highlight-filter
   has to live under the #viewer element because in HCM it's overwritten
   by js at this level, hence links annotations for example didn't
   have the right colors when hovered.
