Support Phoenix generators for authentication strategies

Feature request

Is your feature request related to a problem? Please describe.

The current issue is that the usage of this integration with supabase-ex in phoenix and plug based projects are kinda... cumbersome I would say.

so the idea here is to simplify the implementation and avoid massive meta-programming couple features to actually use different authentication strategies, while also simplifying the migration from phx.gen.auth.

Describe the solution you'd like

to achieve this we need to implement the generators like phoenix does, maybe something

mix gotrue.gen.auth -s oauth -p apple

whether -s stands for --strategy and -p for --provider.

so for each strategy we can implement a custom generator and it should use live view as default but we can think to implement dead view support in the future.

also, we can check https://github.com/ash-framework/igniter for some inspiration ^-^

• implementing this is probably a foundation to extend and then implement supabase-ui for live view
