Fix Tab Trap in SettingsHotkey Custom Control (#7136)

* basic logic working

* Added a literal for ignore flag which cna be shared by all the files

* Added a condition that the other modifier keys should not be pressed

* Added comments to describe each scenario

* sometimes when multiple modified keys were involved the shift+tab key press was also being invoked, so added an additional check in the IsValid function

* use variable for vk_tab

* remove new line before initializing dwextraInfo

* move flag check if the filterKeyboardevent function

* use windows.system.virtualkey.shift instead of defining a constant for the shift key code

* removed latest settings to use internal settings instead. Removed the validity check while still within the hotkey other than if it's tab or shift+tab

* add a function to send input to the system instead of duplicating the send input code

* remove VKSHIFT declaration

* display all shortcuts/keys except tab and shift+tab

* remove header that is no longer needed
