feat: Add support for deferred routes registration

[patricklafrance]

This PR introduces new APIs to support deferred routes registration with the ultimate goal of conditionally adding routes based on feature flags.

What changed

@squide/core

• Updated the ModuleRegisterFunction type to accept a function as the return value.
• Added a completeLocalModuleRegistrations function to complete the second phase of the registration process for local modules.

@squide/webpack-module-federation

• Added a completeRemoteModuleRegistrations function to complete the second phase of the registration process for local remote modules.
• Added a completeModuleRegistrations function to execute completeLocalModuleRegistrations and completeRemoteModuleRegistrations in a single call.
• Added the useAreModulesRegistered hook to re-render the application once all the modules are registered (but not ready).
• Reworked the useAreModulesReady hook to be complimentary to the useAreModulesRegistered hook when deferred registrations are registered. The hook is backward compatible and includes no breaking changes.
• Added a features section to the defineConfig functions options.

What's next

• Adding a generic AppRouter component
• Writing many guides explaining all the APIs that has been added lately
