Cherry-pick #8855 into swift/release/6.0

(copied from swiftlang/swift#74740)

  • Explanation: swift-syntax libraries in compiler has been complied with -enable-library-evolution because the toolchain provides them as a public interface for building plugins (i.e. lib/swift/host/*.swiftmodule). But that was not great for the performance in the compiler. This PR changes that by separating swift-syntax libs for the compiler from the one for the plugins. So the compiler and the plugin now can use different version/ABI of swift-syntax libraries from the compiler. Now swift-syntax for the compiler are compiled without library evolution.
  • Scope: Macro plugins
  • Risk: Mid. This changes the mechanism of in-process plugins significantly. Now in-process plugins are communicate with the compiler using the same messaging serialization with other plugins (i.e. swift-plugin-server, and other executable plugins), instead of directly calling the Macro.Type expansion method. Also, to separate the swift-syntax libraries, this introduces another set of shared swift-syntax libraries in the toolchain.
  • Testing: Passes current test suite.

swift-syntax libraries for compilers are now in 'lib/swift/host/compiler'
