Refactor for `@ChangeTracked` and stylesheets

[carson-katri]

• LiveBinding was replaced with ChangeTracked.
• The pause, play, and seek events were removed. Use the attributes time-control-status and playback-time instead

Here's a small example of how the element can be used:

[!Note] You must provide a phx-throttle or phx-debounce attribute to receive updates for the playback-time.

defmodule MyAppWeb.IndexLive do
  use MyAppWeb, :live_view
  use MyAppWeb.Styles.AppStyles

  def mount(_params, _session, socket) do
    {:ok, assign(socket, playbackTime: 30, isMuted: false, timeControlStatus: "paused")}
  end

  def render(%{format: :swiftui} = assigns) do
    ~SWIFTUI"""
    <VStack>
      <VideoPlayer
        url="https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4"
        autoplay
        playback-time={@playbackTime}
        phx-throttle={1000}
        is-muted={@isMuted}
        time-control-status={@timeControlStatus}
        phx-change="player-changed"
        class="aspect-video"
      />
      <Text class="title">Big Buck Bunny</Text>
      <List>
        <LabeledContent>
          <Text template="label">Playback Time</Text>
          <%= @playbackTime %>

        <Button phx-click="random-time">Random Time</Button>
        <LabeledContent>
          <Text template="label">Muted</Text>
