With the removal of Flash, there is no longer the need to return anything for navigator.plugins and navigator.mimeTypes. These APIs were used primarily for a) probing for Flash player support, or b) fingerprinting. Some sites use these APIs to probe for PDF viewer support. With this change, these arrays will return fixed lists containing a standard list of PDF viewer plugins.
Motivation
Improve interop, remove fingerprinting vector, general API cleanup.

Note that this is not the removal or change of any API, it is merely the return of fixed arrays for these two existing APIs.
