A zircon handle is associated with a koid, kernal object identifier.
Whereas the handle can be duplicated, koid is unique. Two distinct
handles can point to the same kernal object, if their koids are
the same.

This change adds access to koid for a Handle object.

Test: Adds a unittest for koid

This is part of a larger effort to expose the difference between GrDirectContext,
which runs on the GPU thread and can directly perform operations like uploading
textures, and GrRecordingContext, which can only queue up work to be delivered
to the GrDirectContext later.

The Windows, Linux, and GLFW embeddings (which all share a common code
ancestry) pass TextInput.setEditingState selection base and extents
straight through to the shared text model class. The model expects those
values to be valid, but the framework sends -1/-1 for "invalid"
selections, which happen for some empty text cases (e.g.,
TextFieldController.clear()).

This translates those invalid selection values to an empty selection at
the start of the string, as expected by the model.
