Andrew Scott ae0a63ad48 refactor(router): Move preloading to tree-shakeable provider (#46215) ...

Extracting preloading to a provider moves us towards
thinking about a world where `ExtraOptions` doesn't exist to control
behaviors that are opt-in/opt-out. Instead, these behaviors could be
controlled by the presence (or lackthereof) of the providers which has
the functionality. This is relevant to a world in which we no longer
have the `RouterModule` but instead have something like `provideRouter`
where the features are tree-shakeable.

This change _does not_ make the `RouterPreloader` tree-shakeable inside
`RouterModule.forRoot` because the compiler cannot statically determine
whether it's needed. However, in the `provideRouter` world without
`forRoot`, preloading could be exposed through the provider function
instead, making the `RouterPreloader` and `PreloadingStrategy`
implementations tree-shakeable for those that don't use it (which is the
default - no preloading).
