Fulfil only necessary interfaces in each module's module.go

[DimitrisJim]

Raised in #7261 #7261 (comment)

is this solely to fulfil the AppModuleBasic interface we currently assert on line 34? Can't we just fulfil the HasGRPCGateway https://github.com/cosmos/cosmos-sdk/blob/5799c15b90998b1a1474c50695f0d5063af6bd38/types/module/module.go#L52 interface?

From what I understand we can remove the assertion on AppModuleBasic and only use HasGRPCGateway.

I think we should comb through all of the modules to ensure we have the minimum amount of interface assertions needed.

Should be done after #7261 and relevant PRs for it are merged.
