fix(publish): Don't strip non-dev features

First, we added support for stripping of local-only dev-dependencies.
This was dual-implemented for `Cargo.toml` and `Summary`.

This left off stripping of `dep/feature` that reference dev-dependencies
(enabling features within dev-dependencies).
When we fixed this, we again dual-implemented it.

The `Cargo.toml` version was correct but the `Summary` version was
instead stripping too many features,
particularly features that reference renamed dependencies.
We didn't have tests for this case and it wasn't caught earlier because
crates.io re-generates the `Summary` from `Cargo.toml`, ignoring what we
post.
That makes this only show up with custom registries that trust what
Cargo posts.

Rather than fixing the `Summary` generation, I remove the
dual-implementation and instead generate the `Summary` from the
published `Cargo.toml`.
Unfortunately, we don't have access directly to the packaged
`Cargo.toml`.
It could be passed around and I originally did so, hoping to remove use
of the local `Package`.
However, the local `Package` is needed for things like reading the
`README`.
So I scaled back and isolate the change to only what needs it.
This also makes it easier for `prepare_transmit` callers.
Fully open to someone exploring removing this extra `prepare_for_publish` in the future.

Fixes #14321
