Move //mojo/{public, edk} underneath //third_party
This CL move //mojo/public and //mojo/edk to live in the following locations: - //third_party/mojo/src/mojo/public - //third_party/mojo/src/mojo/edk It moves the related gypfiles from //mojo to //third_party/mojo and updates them as necessary to account for the file moves. It also updates clients of the mojo SDK and EDK targets in both GYP and GN. (Note that for GN, the mojo SDK and EDK build systems are maintained in the Mojo repo and designed to be flexible wrt the location of the SDK/EDK in a client repo, so no changes are needed. This CL does not update include paths to the code being moved to limit the number of moving parts, instead relying on the include_dirs that the SDK and EDK targets supply to their direct dependents to ensure that include paths continue to resolve correctly.
