White surfaces on components

[Thunear]

We need white surfaces on our components. Using background-default for this does not fit the pattern and introduces issues when we try to create logic for surfaces.

• Test neutral colors with alpha
• Test alpha blending and WCAG contrasts

Meeting 17/12: @mimarz @mrosvik @Febakke @Thunear @eirikbacker + 2 extra members from Mattilsynet

• We decided on making Surface Default in light mode white, and make the transition to Surface hover- and active states less noticeable. This way the grey color will work better on colored backgrounds.
• For neutral in dark mode we decided on using alpha values. This might work better since surfaces are never completely black.
• If the user wants grey surfaces, this color has to be added manually.

I will test this new approach and call for a new meeting a bit later.
