Feat: support lazy compile of routes

[ClarkXia]

Enable routes compilation will help to optimize the dev startup performance of an application with a large number of pages, each route will only be built when it is actually accessed.
This is not to be confused with webpack's experimental.lazyCompilation, which can also be enabled by user configuration.
