Output the dependency status file as JSON

Is your feature request related to a problem? Please describe.
In my industry there is currently a need to keep track of the software versions of all dependencies for a given project. VCPKG, fortunately, provides such a list as a status text file located at ./vcpkg/installed/vcpkg/status. Unfortunately, this output is not written in an industry standard format. Which means I require writing my own custom parser to parse this dependency list in order to generate documentation for my clients.

Another issue that I am having is the status file doesn't exist in ./installed/vcpkg when I run ./vcpkg export it only exists in the original directory I clone vcpkg into. I need this dependency file exported with the libraries so that each snapshot of vcpkg I make for a given project can trace its software dependencies.

Finally, part of tracing software dependencies is knowing their original source location. Currently, this can be found in the ports' CONTROL file labeled as Homepage. In order for me to successfully parse and provide the correct information to my clients, I need access to this Homepage from within the status file as well.

Proposed solution
I propose that this file, at a minimum, is generated as status.json or dependencies.json so that users of vcpkg may parse this file with currently available json parsers.
I propose that this status.json file be included in the export list for ./vcpkg export
I propose that the CONTROL file Homepage be included as part of the status.json dependencies.

Describe alternatives you've considered
My current work around is to write my own custom text parser to parse out the dependencies from the status file. Then, I need to take that dependency list and do a name match of the ports so that I may parse the CONTROL files for each Homepage. Finally, during the pipeline stage of my vcpkg, copy the status file into the vcpkg-export.zip file that my pipeline produces.

Additional context
The end goal is to parse the vcpkg software dependencies so that I may present the data to my clients as needed.

I really like the sound of this proposal.
