[PATCH yew-widget-toolkit-assets 1/3] dropdown: add class for dropup mode

[Shannon Sterz <s.sterz@proxmox.com>]

a dropup is a dropdown that is rendered above the corresponding input
element. in such scenarios reversing the column flex direction is
desirable for better ux. for example, if a `Combobox` specifies a
filter, this would now render the filter box closer to the dropdown's
input element instead of on top of the dropdown list.

this is part of the fix outlined in [1] and makes dropdowns more
adaptive respective to how they can be rendered. the `!important` is
needed to override `.pwt-flex-direction-column` as it also uses
`!important` already.

Notes:
    this came up in peat which now also has a couple of really long
    comboboxes. affecting ux detrimentally. so move the stop-gap here to
    at least have a consistent experience.
