This will enable forwards compatibility for `positioning="top-layer"` with popover.
BREAKING CHANGE: refactor `fixed` property to `positioning="fixed"` in Menu and `menuFixed` to `menuPositioning="fixed"`

BREAKING CHANGE: if overriding margin on a dialog's content, swap it to padding. If a dialog's slotted first or last child has built-in margin (such as `<h3>` or `<p>`), remove the top/bottom margin as needed (since margin swapped to padding, there's no more margin collapsing).

BREAKING CHANGE: See https://github.com/material-components/material-web/discussions/4675 for more details.
Dialogs use the native `<dialog>` interface, which uses a `<form method="dialog">` to set up dialog actions.
```html
<md-dialog>
<div slot="headline">A simple dialog</div>
<form id="form" method="dialog" slot="content">
This is a dialog with text content.
</form>
<div slot="actions">
<md-text-button form="form" value="close">Close</md-text-button>
<md-text-button form="form" value="ok">OK</md-text-button>
</div>
</md-dialog>
```

BREAKING CHANGE: Fullscreen dialogs weren't matching spec, so we're removing them for now to avoid future breaking changes. They will be re-added later.
