Fix text-input support for new API

Update text input support to upstream text-input protocol v2 from
wayland-protocols. Remove support for input-method protocol for now.

Map text-input protocol on compositor side to the Qt input method API,
this allows to use any qt platform input method on compositor side
(especially qtvirtualkeyboard). Add support for qtvirtualkeyboard to
pure-qml example.

Implement all missing functions of the text-input protocol.
