Matan Lurey 761720dc4c [Impeller] Implement TextDecoration (i.e. dashed lines) (flutter/engine#45041) ...

Closes https://github.com/flutter/flutter/issues/126673.

Ideally, this would be an `#ifdef`, but currently Impeller is a runtime
flag, for reasons (CI capacity?)

~~To be able to write tests, I'd need
https://github.com/flutter/flutter/issues/133264 completed.~~ Edit:
