feat: add support for generic interfaces

[tomMoulard]

This PR adds support for generic interfaces to be mocked.

Here is the basic example:

// interfaces.go
type Banana[T, U any] interface {
	Tree(T)
	Flower() U
	Pudding()
}

// mock_test.go

// mocktail:Banana

// interfaces_test.go
var b Banana[string, int] = newBananaMock[string, int](t).
	OnTree("a").Once().
	OnFlower().TypedReturns(1).Once().
	OnPudding().Once().
	Parent
