This extracts the examples that are in flutter/engine@main/lib/ui/text.dart into examples in the examples/api/lib/ui directory and adds some simple tests for them.
Also, fixes some inconsistent test file naming.
This is step 1: the next step is to remove the examples from the dart:ui code.
Before this change, it was possible to select and copy obscured text from a text field.
This changes things so that:
- Obscured text fields don't allow copy or cut.
- If a field is both obscured and read-only, then selection is disabled as well (if you can't modify it, and can't copy it, there's no point in selecting it).
