[Feature] match routes by pattern in splitted server

It would useful to be able to match multiple routes with single regex pattern in `SplittedFunctionOptions.routes`, as now every route should be listed in the config.
```ts
// Before 
-      routes: [ 'pages/app/index', 'pages/app/products', 'pages/app/products/[id]'],
// After
+      routes: [ 'pages/app/:path*'],
```
