Hajime Hoshi db24fb7c6b exp/textinput: clear queued states when text field is unfocused
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.

Updates #3382
Closes #3429
