patterns: Move logic to draw patterns into separate class (#472)

Browse Source 
* refactor(patterns): add visitor interface

* refactor(patterns): add public accessors

* refactor(patterns): add method to get pattern value

* refactor(pattern): make some methods public

* refactor(pattern): extract code to draw GUI

* refactor(patterns): remove GUI related code from patterns

* refactor: move common GUI function from pattern to pattern_drawer

* refactor(pattern_drawer): extract common code into methods

* refactor: rename ImGuiDrawer -> PatternDrawer

* refactor(patternr): move displayEnd into PatternDrawer

* refactor: use ArrayPattern concept to restrict argument type
