bundle-analyzer: use <Select> and multiselect for top bar (#87254)

The top bar is getting quite wide with all of its button toggle groups.
This:

- Converts the Compressed/Uncompressed and Client/Server toggles to
shadcn `<Select>`s
- Adds a custom `<MultiSelect>` implementation since this is missing in
shadcn. This composes shadcn’s popovers and a series of checkboxes,
along with accessibility attributes and keyboard shortcuts.
- Uses this `<MultiSelect>` for the type filter
- Removes the divider between these since there aren’t any groups left
to divide
