Synchronize menu state in drawing sample with actually selected graphics renderer.

Browse Source 
Because graphics renderer is not only selected via menu but also directly in the application (in MyFrame::OnShow) there is necessary to update menu items responsible for selecting graphics context to represent current state of the application.
This is done in EVT_UPDATE_UI handlers where there is checked what graphics renderer is currently in use and state of the menu items is updated accordingly.

Closes #16971.
