Steven Wu da10a02231 [Macro] Fix bugs in macro dependency scanning ...

Fix few issues from previous implementation from explicit module build
with macros and accurate macro dependency scanning in
https://github.com/swiftlang/swift/pull/73421.

First, there is a crash when propagating the macro dependencies. It
turns out that the current macro plugin implementation doesn't need the
downstream users to know about the plugin search path from the upstream
dependencies.

Secondly, fix a bug that the swiftinterface that has macro usage won't
build because the build command doesn't inherit the plugin search path
option.

Finally, add JSON output for macro dependencies so it is easier to
debug the macro dependencies.
