CompiledRouteCollection->getRoutes creates Routes from $attributes every time called

[robchett]

This was raised as a slowdown when using compiled routes over dynamic routes.

We tracked this down through

Livewire\Features\SupportBrowserHistory::getRouteFromReferer
Illuminate\Routing\CompiledRouteCollection::match
Illuminate\Routing\CompiledRouteCollection::handleMatchedRoute
Illuminate\Routing\CompiledRouteCollection::checkForAlternateVerbs
Illuminate\Routing\CompiledRouteCollection::get <-- this is loops for each method (GET/POST/PATCH/DELETE/OPTIONS/HEAD)
Illuminate\Routing\CompiledRouteCollection::getRoutesByMethod

We have a compiled list of 400+ routes and this is consuming 200ms+ of a 1.6s page load (~15%).

Changing this to convert from array -> Route just once will reduced this overhead by 5/6ths.
