RFR: 8258426: Split up autoconf/version-numbers and move it to conf dir [v2]

[Magnus Ihse Bursie]

> The file `make/autoconf/version-numbers` is plagued by a two-fold problem: first of all, it's a configuration file, not a part of autoconf, so it should reside in `make/conf` instead of `make/autoconf`.
> 
> Secondly, contrary to the name, it does not only contain version numbers, but also the branding properties (company name, product name, etc). This should be split out into a separate branding configuration file.
> 
> This is the last patch in the series of moving configuration into `make/conf`.
