[issue12279] Add build_distinfo command to packaging

[Éric Araujo]

packaging.command.cmd already has this method: it was renamed to get_reinitialized_function, to better match other method names.

Yes, that’s a workaround :)  Have you tested writing to build.build_lib (see my previous message)?  The test command for example runs the tests in the build dir, to test what will really get packaged, and to allow build-time 2to3 conversion.

One part of properly implementing a build_distinfo command that can be tricky is the .dist-info/RECORD file.  If you just move the code from install_distinfo, the locations in the RECORD file will not be the actual locations of the files.  Possibilities:
1) don’t generate RECORD at all → invalid PEP 376
2) generate RECORD with paths to the files in the build dir
3) other?
