Add KeyboardEventCodeInteractiveTest

Add KeyboardEventCodeInteractiveTest to test ui_test_utils::SendKeyPressSync()

KeyboardEventCodeInteractiveTest starts a web page to record all the
KeyboardEvent.code it received, sends several key presses through
ui_test_utils::SendKeyPressSync() and verifies whether the record is expected.
This test ensures KeyboardEvent.code can be correctly set by using
ui_test_utils::SendKeyPressSync() function. After change
https://codereview.chromium.org/2939283002/, this test should pass on all
platforms.
