feat: Add ability to pass routes into configuration

[cbaker6]

Pass routes using:

@main
enum Entrypoint {
    static func main() async throws {
        var env = try Environment.detect()
        try LoggingSystem.bootstrap(from: &env)

        let app = try await Application.make(env)

        // This attempts to install NIO as the Swift Concurrency global executor.
        // You should not call any async functions before this point.
        let executorTakeoverSuccess = NIOSingletons.unsafeTryInstallSingletonPosixEventLoopGroupAsConcurrencyGlobalExecutor()
        app.logger.debug("Running with \(executorTakeoverSuccess ? "SwiftNIO" : "standard") Swift Concurrency default executor")

        // exampleRoutes is a function consisting of all of your own routes
        try await parseServerSwiftConfigure(
            app,
            using: exampleRoutes
        )
        try await app.execute()
        try await app.asyncShutdown()
    }
}
