Wayland text input could not switch input method.
When using an input method editor (e.g. input Chinese),
switching the input method (e.g. input English -> input Chinese)
during input text was not supported.
Resolve the issue by calling `zwp_text_input_v3_disable` every time
after receiving a `leave` event, and call `zwp_text_input_v3_enable`
every time after receive `enter` event, when text input is enabled.
