Support wildcard stack for command `pack buildpack package`

[fg-j]

Summary

When attempting to use pack buildpack package to package a composite buildpack that contains a buildpack whose [[stacks]] only contains one entry -- id = '*' and a buildpack that contains non-wildcard stacks, packaging fails with a stack incompatibility error

ERROR: no compatible stacks among provided buildpacks

despite the buildpacks actually being compatible.

---

Reproduction

Steps

1. Clone my fork of the buildpacks samples repo and checkout the package-repro branch

2. Using pack v0.24, run

 pack buildpack package my-buildpack --config ./package.toml

Current behavior

Packaging step fails with:

ERROR: saving image: no compatible stacks among provided buildpacks

Expected behavior

Expected packaging to succeed because the git buildpack specifies stack wildcard
and since * is an allowed stack id.

Converting this into a feature since it's technically a bug but more of a missing feature given that the buildpack API changed after the initial implementation.

We're happy to take any contributions for these changes. I believe they should be a "good first issue".

[sambhav]

@jromero I think this would still be a bug fix given that #1234 added support for it. Would you be open to releasing a patch version of pack with this and a bunch of other wildcard stack fixes? This is currently blocking some work on our side. Happy to do the leg work to get the PRs out.

[jromero]

I'd be happy to support a patch if it's pressing and we can get a PR up from the latest released commit.

I say all this as long as there's no push back from @dfreilich ☺️
