Support non-basic type constraints

Nobody has claimed this yet.

This issue is to track the limitation that was mentioned in the description of #175.

Consider the following interface:

```go
type Sorter[T comparable] interface {
Sort(slice []T) []T
}
```

When generating a mock using moq v0.3.2, the following implementation check is created:

```go
var _ Sorter[comparable] = &SorterMock[comparable]{}
```

This code is not valid due to the following reason:

> cannot use type comparable outside a type constraint: interface is (or embeds) comparable

Reproduce the issue with the Sorter[T comparable] interface shown in the report and inspect the code-generation path that emits the implementation check. Done means the generated mock for this non-basic constraint compiles without producing Sorter[comparable] in an invalid context; add or run a regression test if the repository has an appropriate generator test entry point.
