[Macros] Add 'LibraryPluginProvider'
LibraryPluginProvider is a PluginProvider that can load shared library plugins at runtime.
in the near future, combined with https://github.com/apple/swift-syntax/pull/2301, in ASTGen, we can easily create in-process "plugin server" like
@_spi(Compiler) import SwiftCompilerPluginMessageHandling
let inProcPlugins = CompilerPluginMessageHandler(provider: LibraryPluginProvier.shared)
// Load in-process plugins.
let response = inProcPlugins.handleMessage(
HostToPluginMessage.loadPluginLibrary(libraryPath: path, moduleName: module)
)
// Expand macros.
let response = inProcPlugins.handleMessage(
HostToPluginMessage.expandFreestandingMacro(...)
)
so we can treat in-process plugins as just another plugin server
