Felix Berger cb4c12b611 [clang-tidy] performance-unnecessary-copy-initialization: Create option to exclude container types from triggering the check. 
Add string list option of type names analagous to `AllowedTypes` which lets
users specify a list of ExcludedContainerTypes.

Types matching this list will not trigger the check when an expensive variable
is copy initialized from a const accessor method they provide, i.e.:

```
ExcludedContainerTypes = 'ExcludedType'

void foo() {
  ExcludedType<ExpensiveToCopy> Container;
  const ExpensiveToCopy NecessaryCopy = Container.get();
}
```

Even though an expensive to copy variable is copy initialized the check does not
trigger because the container type is excluded.

This is useful for container types that don't own their data, such as view types
where modification of the returned references in other places cannot be reliably
tracked, or const incorrect types.
