Fix Cursor States On Windows (#6725)

* [Ava]: Fix Cursor States On Windows

It's been sometime since the last PR #5415 was made and last time i was waiting for Ava 11 to be merged before re-writing the code and along the way forgot about the PR.

Anyway this PR supersedes both #5288 and #5415, and fixes issue: #5136

* Now, the bounds for which the cursor should be detected in renderer should be accurate to any scaling / resolution, taking into account the status and the menu bar. ( This issue was partially resolved by #6450 )

* Reduced the number of times the cursor updates from per frame update to updating only when the cursor state needs to be changed.

* Fixed the issue wherein you weren't able to resize the window, because of the cursor passthrough which caused the cursor to reset from the reset icon or flicker.

* Fixed the issue caused by #6450 which caused the cursor to disappear over the submenus while cursor was set to always hide.

* Changed the cursor state to not disappear while the game is being loaded. ( Needs Feedback ).

* Removed an unused library import.

* PR feedback

* Fix excessive line breaks and whitespaces and other feedback
* Add a check before calculating cursor idle time, such that it calculates only while the cursor mode is OnIdle.

* PR Feedback

* Rework the cursor state check code block
