Dump symbol graph command doesn't support 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 dump symbol graph command directly invokes the native build system, and uses the build plan, which is only available for that build system. Instead, it should be possible to specify another build system, such as the swiftbuild build system, and use alternate means to get the symbol graph arguments for the requested targets. The build parameters can potentially provide this information.
