[go_router_builder] Adds name parameter to TypedGoRoute and supports its generation. (#3665)

This PR allows for generating `TypedGoRoutes` by defining a custom name and forwarding it to the underlying `GoRoute` this is needed when working with Analytics services such as Google analytics that use the name to log the page in their systems.

Fixes [#120102](flutter/flutter#120102)
