LibWeb/CSS: Use double in `CSSHWB::to_color()`

See previous the commit description for more details about the floating
points operations.

The hwb test cases in `css-color-functions` are now rendered identically
to what firefox does (I haven't checked the others tests, but they
aren't affected by this commit).
