Hang a menu on its menu button rather than the trigger's wrapper

<x-menu> named its CSS anchor on the <span> around the trigger slot.
A trigger taken out of the flow, such as <x-button fab> fixed to the
bottom corner of a phone's window, left that span behind as an empty
box where the page put it, and the menu opened there. menu.js now moves
the name onto the menu button, beside any name the button already
carries for its tooltip, and moves it again whenever a Livewire morph
puts the server's attributes and a fresh name back. The wrapper keeps
the name until Alpine starts, or when there is no menu button.

A menu that fits neither below nor above its start edge now also tries
the opposite side and end together, so a default-position menu on a
FAB in the bottom-right corner opens above it, end-aligned. Before, it
fell back to its base position and overflowed the window.

This also applies to <x-fab-menu>, <x-account-menu>, <x-split-button>
and the <x-section-nav> picker, which share menu.js.
