8261231: Windows IME was disabled after DnD operation

[dmarkov20]

The function InvokeInputMethodFunction() is responsible for invocation of IME API. Typically it uses PostMessage() to execute corresponding IME function on the toolkit thread but if DnD operation takes place SendMessage() is used. The state of m_inputMethodWaitEvent event object remains signalled after SendMessage() execution. That causes failure of subsequent IME functions calls via PostMessage().

Fix:
SendMessage() and PostMessage() calls inside InvokeInputMethodFunction() should be synchronised. The state of m_inputMethodWaitEvent event object must be reseted right after SendMessage() execution.

Change looks good and i haven't found any side-effects during testing. Could you please add the label to the bug noting reason for absence of the regression test, like noreg-hard or something?
