feat: Move AppModule.BeginBlock and AppModule.EndBlock to extension i…

…nterfaces (cosmos#12603) ## Description Most modules right now have a no-op for AppModule.BeginBlock and AppModule.EndBlock. We should move these methods off the AppModule interface so we have less deadcode, and instead move them to extension interfaces. 1. I added `BeginBlockAppModule` and `EndBlockAppModule` interface. 2. Remove the dead-code from modules that do no implement them 3. Add type casting in the the module code to use the new interface Closes: cosmos#12462 --- ### Author Checklist *All items are required.
