[REF] web: remove o-get-most-contrast function

Browse Source 
As the `color-contrast` function provided by BS5 basically fulfill the
same need as the custom `o-get-most-contrast` function and the later one
isn't used, we can safely remove the custom one.

closes odoo/odoo#96626

Note: last (and only) usage was in mrp_workorder's tablet view.
