The session's state queue buffers input events that arrive between a commit-end and the next session start, which is needed when multiple keys are pressed simultaneously (#3382). However, when a text field was unfocused, keystroke events continued to be queued by the platform layer and were replayed when a field was next focused, causing unexpected text to appear. Clear the queued states in Field.cleanUp(), which is called when a field is blurred. This preserves the queue for simultaneous keypresses within a focused field while discarding stale input from unfocused periods. Also refactor textInput to move the session field and theTextInput variable to the cross-platform textinput.go, with each platform defining only a textInputImpl with platform-specific fields.
