UX: Automatically collapse admin page header buttons on mobile (#29040)

This commit attempts to improve the mobile experience for
admin page header and subheader by automatically collapsing
all action buttons in these components into a DMenu when viewing
mobile.

This is done by using different "list" wrapper components and a
DMenu trigger and a DropdownMenu on mobile only, and uses has-block
to determine whether to render the DMenu trigger at all.

This also removes the `PluginOutlet` in `AdminPluginConfigPage`, it
was too inflexible for this `DropdownMenu` case, and since the `:actions`
were always rendering we couldn't rely on `has-block`. A new plugin API,
`registerPluginHeaderActionComponent`, has been introduced instead to
replace it.
