Draw the snackbar host without Tailwind

Browse Source 
Plan step 36 (actions). <x-toast> renders data-md-toast with
data-md-position, its snackbar data-md-toast-snackbar with a bound
data-md-two-line, data-md-toast-content with a bound
data-md-toast-wrap, and data-md-toast-action/-dismiss; no class list.
toast.css draws SnackbarTokens' inverse surface, 48/68px container,
the two 40px controls reaching 48px targets with their own state
layer and touch target (ACT-18), the enter transition and the
position-start margin that grows from medium.

data-toast becomes data-md-toast-snackbar and data-toast-action
becomes data-md-toast-action (snackbar.js, navigation.js's
hide-on-scroll guard, NavigationBarTest, CommunicationTest); a new
data-md-toast-dismiss hook names the close button. ToastTest is
rewritten on the hooks and ComponentStylesheet. CommunicationTest
gains the owed tests: an actioned snackbar past the default timeout,
Escape on a focused one, the live region before any message, and the
two-line height with Alt+G reaching the action from elsewhere on the
page.
