[presentation-api] Pull Request: Restrict API to secure contexts

mfoltzgoogle has just submitted a new pull request for 
https://github.com/w3c/presentation-api:

== Restrict API to secure contexts ==
Address Issue #380: Authenticity of screen selection permission is 
problematic in insecure contexts

This restricts the use of Presentation API to secure contexts through 
the use of `[SecureContext]`.  Also:

- Mixed content check is simplified
- Examples are updated to use `https:`
- Use correct term for _a priori authenticated URL_
- Remove xref to _potentially trustworthy origin_ as it's unused
- Remove discussion of insecure origin display
