* Add telemetry for keyboard button usage in graphing mode

* Added the diagnostics for EquationAdded and FunctionAnalysis

* Added remaining diagnostics events for graphing calculator

* Fix proj files to include the IsStoreBuild condition. Move the Delayer class to the Calculator/Utils folder

* Ensure the variable textbox has focus before logging diagnostics

* Move maxVariableCount check into the tracelogger class

* Created enums and updated the slider value changed method to remove the variable from the map after the log method is called

* Re-enable hidden lines when the expression is updated

* Fixed extra line in grapher.h and removed the conditional logging for variable count

* Updated logging per PR feedback

* Updated variable logging and fixed issues in the IsEquationLineDisabled binding the EditTextBox control.
