This tool was supposed to be used for internal debugging purpose on Android devices. It already supports RKP uploading CSR format. Extend this tool to support Widevine uploading format: JSON csr and make this format as default output for AOSP (non-GMS) partners. A later change will move it to its own aosp/ directory. Test: run "wv_factory_extraction_tool json_csr" on Pixel 9 Bug: 414642286 Change-Id: I9cf4e9696d32201cc1ad70b6bee7932f7126a4ba
