[Presentation] Migrate all usages of EuiPage*_Deprecated

[nreese]

closes #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.

Looked through the code and everything looks good! Also ran this locally and read through the examples. We'll definitely need to revisit this, as there is a lot more we could demonstrate + plenty of ways to streamline the content but LGTM!

Hopefully the conflicts with #159837 won't be too bad!
