Use drawOnState() for buttons precessing and cache buttons' position for event handler loop

[Districh-ru]

This PR affects most of the dialogs in the engine including the main menu.

It replaces le.isMouseLeftButtonPressedInArea( button.area() ) ? button.drawOnPress() : button.drawOnRelease(); with button.drawOnState( le.isMouseLeftButtonPressedInArea( buttonArea ) ); and do buttonArea cache not to call .area() with all its calculations on every loop.

It also modifies some dialogs that can be also called by the mouse right click to have its own event handler loop to reduce some checks (e.g. unit dialog, build dialog). And in some dialogs it skips the possibly unused buttons initialization making them unique_ptr, in example in Hero dialog: DISMISS and PATROL buttons.

While testing this PR you should check rendering of the buttons (press/release) and their interaction with the mouse cursor (right press, left click).

This PR does not fix rendering issues that are present in the master build.
