The package migrate command doesn't work with the swiftbuild build system

[cmcgee1024]

Is it reproducible with SwiftPM command-line tools: swift build, swift test, swift package etc?

• Confirmed reproduction steps with SwiftPM CLI. The description text must include reproduction steps with either of command-line SwiftPM commands, swift build, swift test, swift package etc.

Description

The swiftbuild build system doesn't support providing a build plan, since that is specific to the native build system, and will throw an error when that is called. The migrate command should use different means to get the build modules, possibly the ModulesGraph instead to get the list of modules to acquire the FixIts for the migration.
