Support different text input protocols

from clients and one compositor at same time.

For compositor side, just need to have TextInputManager and
QtTextInputMethodManager together.

For client side, set QT_WAYLAND_TEXT_INPUT_PROTOCOL env to choose:

* If the env is unset(empty) or invalid, it will search
qt_text_input_method_v1 and zwp_text_input_v2 in order
* Set as "qt_text_input_method_v1" or "zwp_text_input_v2" if compositor
supports
* Set as "zwp_text_input_v2;qt_text_input_method_v1"
