[PTRun][WindowWalker]Don't hang when closing an unresponsive window (#33167)

* add(windowWalkerComponents): added a "Responding" variable signifying if a process is responding or not

* add(win32NativeMethod): added "SendMessageTimeout" method in the common Win32 namespace

* refactor(windowWalkerWindow): added an implementation of the helper function for closing the window using the newly defined method

refactor(windowWalkerWindow): added a thread to run, whenever "CloseThisWindow" is called

* refactor(resultHelper): used localizable strings for printing the responding text

add(resources): added "Not Responding" localizable text to the resources file

* refactor(resultHelper): refactored the message in case of a "Not Responding" task

* refactor(resultHelper): modified the formatting of the subtitle

* refactor(window): refactored the helper function and removed the unnecessary variable

* refactor(windowProcess): changed the variable name from "Responding" to "IsResponding"

* add: added try-catch to isResponding getter
