Pare down the iOS WebContent Process sandbox to only things actually needed by WebKit.
Created attachment 329046 [details]
Pare down the set of sandbox exceptions in the iOS WebContent process sandbox to just
those services actually in use:
1. Remove unused code.
2. Instead of defining a 'UIKit-app' function and calling it, just declare the individual sandbox
commands inline. This will allow them to be more easily consolidated with other parts of the
sandbox in a future step.
These sandbox edits should not produce any change in behavior, since these are user interface features used by applications, not things needed by WebKit.
