Re-enable possibility to center the FindReplaceDlg on Notepad++ main window

* add goToCenter to hotkey check in IDM_SEARCH_(FIND|REPLACE|FINDINFILES|MARK)

Before commit aa69711d it was possible to center the dialog on Notepad++ using a second CTRL+F but was lost during the implementation of #10019, #10177.

This will re-add the function:
* When the hotkey used is not associated with the current tab, it will switch to the new tab (as before).
* If the hotkey used is associated with the current tab, it will center the FindReplaceDlg on Notepad++.

Fix #9201, close #11323
