Issue Description

When running a dart pub global run of an activated package that has dependencies not compatible with current sdk (most likely due to a new package:_macros version'

Will (now, after #56930) give a message like:

The package `protoc_plugin` as currently activated cannot resolve to the same packages.

Try reactivating the package.
`dart pub global activate protoc_plugin`

This can be a bit confusing, as it doesn't explain what went wrong.

This is a follow-up to #56930

What is the fix

We add a summary of the packages that would have to change for the current activation to be valid.

> _macros 0.3.3 from sdk dart (was 0.3.2 from sdk dart)

And if we can detect that the incompatibility stems from a change in an sdk package version we give a specific error message:

The current activation of `protoc_plugin` is not compatible with your current SDK.

Why cherry-pick

To improve the error message when upgrading to dart 3.6.0

Summary: The dart pub global run command gives a confusing error message when an activated package has dependencies incompatible with the current SDK. The fix provides a more informative error message by summarizing the incompatible packages and indicating if the incompatibility stems from a change in an SDK package version.
