Subcommand to list which package config overwrites which phases

[matthiasbeyer]

It turned out that finding all packages that overwrite a specific phase would be beneficial for package maintainers.

[christophprokop]

maybe more helpful like the output of:

git config -l --show-origin

perhaps:

butido analyse pkg-configs ffmpeg [=5.1.4]

to show for a specific package+version from which pkg.toml the phases originate, i.e. where/when the layering of pkg.toml files takes place
e.g.

[...]
pre-configure  ffmpeg/pkg.toml
configure      ffmpeg/pkg.toml
make           ffmpeg/5.1.4/pkg.toml
pre-install    pkg.toml
install        ffmpeg/5.1.4/pkg.toml
[...]

maybe add an option to only show the changed/layered ones and not the default phases taken from top-level pkg.toml
