* [REF-2098] Allow overlay Close components to have on_click handlers
The child of the Radix *Close components are passed `asChild`, meaning they are
treated as the direct child of the Close itself. This causes the `on_click`
handler attached to such an element to override the default `on_click` behavior
of the Close, which is to close the overlay, thus breaking the desired behavior
of the Close component.
When creating a Close component, if the child has an `on_click` handler, then
internally wrap it in a `Flex` so that the `Flex` gets the `asChild` treatment,
and both the default on_click and the child's on_click are both fired.
Bonus fix: pass `asChild` when constructing the `DrawerClose` to avoid a
<button> in <button> warning in the browser console, because the Drawer does
NOT pass `asChild` to the Close by default.
* Move Trigger logic to RadixThemesTriggerComponent base class
Apply trigger logic to Trigger, Close, Cancel, and Accept components; including
hover_card and dropdown_menu.
