Title: [ExternalSource] Store downloaded external source podspecs as JSON, evaluated from the context of the source directory

Closes https://github.com/CocoaPods/CocoaPods/issues/2875.
Also stores podspecs in the sandbox as JSON.
I will write up a changelog entry if this approach is deemed acceptable.
