Fix Replace All action not notifying plugins of modification regression

Add NPPN_GLOBALMODIFIED to notify plugins that the current document is just modified by Replace All action.
	//scnNotification->nmhdr.code = NPPN_GLOBALMODIFIED;
	//scnNotification->nmhdr.hwndFrom = BufferID;
	//scnNotification->nmhdr.idFrom = 0; // preserved for the future use, must be zero

For solving the performance issue (from v8.6.4), Notepad++ doesn't trigger SCN_MODIFIED & other Scitilla notifications during Replace All action anymore.
Plugin devs should monitor NPPN_GLOBALMODIFIED instead. This notification is implemented in Notepad++ v8.6.5.
