ignore whole types in addition to members (fully qualified)

[tyroguru]

Summary

Our current mechanism for ignoring members is just that - members only. This change extends this allow stubbing of members by type.

namespace X {
  struct Foo {
    int a, b, c;
  };

  struct Bar {
    int x, y, z;
  };

  struct FooBar {
    Foo f;
    Bar b;
  };
} // namespace X

With the above definition to stub out FooBar->Bar you could either stub by member:

[[codegen.ignore]]
type="X::Foo"
member = ["b"]

or you can stub by type:

[[codegen.ignore]]
type="X::Bar"

Note this changes the extant behaviour. Now types MUST be fully qualified for them to match. If they are not specified as fully qualified than stubbing won't work as expected and we'll attempt to capture that member/type .

Test plan

I've altered the ignored integration tests to modify the original test and add 2 more.
