[Presentation] Migrate all usages of EuiPage*_Deprecated (#161496)

closes https://github.com/elastic/kibana/issues/161428

PR also updates examples title. Instead of naming the embeddable used,
the title now reflects what the example demonstrates.
* "Hello world embeddable" -> "Render embeddable"
* "Todo embeddable" -> "Update embeddable state"
* "List container embeddable" -> "Groups of embeddables"
* "Dynamically adding children to a container" -> "Context menu"

There is a lot more that could be done to enhance these examples, but I
did not want to get more side tracked then I already did.

-            <p>
-              The reason to use a container embeddable instead of just a custom react component is
-              because it comes with helpful methods to store the state of all its children
-              embeddables, listeners to clean up the input state when an embeddable is added or
-              removed, and a way to pass down the container embeddable&#39;s own input to its
-              children. In the above example, the container did not take any input. Let&#39;s modify
-              it so it does.
-            </p>
-            <p>
-              In this Searchable List Container, the container takes in a search string as input and
-              passes that down to all its children. It also listens to its children that output
-              `hasMatch`, and removes them from the list when there is a search string and the child
-              doesn&#39;t match.
-            </p>
-            <p>
-              The first HelloWorldEmbeddable does not emit the hasMatch output variable, so the
-              container chooses to hide it.
-            </p>
-
-            <p>
-              Check out the &quot;Dynamically adding children&quot; section, to see how to add
-              children to this container, and see it rendered inside an `EmbeddablePanel` component.

-              If the use case arose, it wouldn&#39;t be difficult. In the mean time, it&#39;s good
-              to understand that children may ignore input they don&#39;t care about. Likewise the
-              container will have to choose what to do when it encounters children that are missing
