feat: add settings-menu

[luwes]

• [x] keyboard control requires fine tuning. focus to expanded submenu when hidden to shown settings menu

test URL: https://media-chrome-git-fork-luwes-settings-menu-mux.vercel.app/examples/vanilla/control-elements/media-settings-menu.html

this change adds new settings-menu and settings-menu-item elements and logic to handle submenus with customizable headers, back button, chevron icons, etc...

the case of a settings-menu in another settings-menu is not yet tried or implemented, it's a more rare case I'd like to add later.

the settings-menu-item has a description slot which automatically gets populated with the submenu checked item text. it's possible for the developer to opt-out by setting a slotted description element.

all icons can be customized with slots, the headers of the menu can be customized with a slot or just the title keeping the back button intact.

If you open a sub-menu and then resize the player the sub menu bleeds out of the player
