[Bug 25923] The mechanism for checking key system support should be asynchronous

https://www.w3.org/Bugs/Public/show_bug.cgi?id=25923

--- Comment #47 from David Dorwin <ddorwin@google.com> ---
Note: The replacement of isTypeSupported() with requestMediaKeySystemAccess()
means it is no longer practical to "discover" key systems by walking a tree.
For example, checking "com.example" then "com.example.somesystem" then
"com.example.somesystem.1_5".

This seemed unlikely to be supported or used much in practice, so this probably
isn't a big loss.
