CollapsingHeader: Added support for ImGuiTreeNodeFlags_Bullet and ImGuiTreeNodeFlags_Leaf on framed nodes. (#2159, #2160)
The Bullet and Leaf ImGuiTreeNodeFlags are now taken into account for Framed/CollapsingHeader tree nodes as well. TreeNodeEx() can be used to specify these flags. A choice was made to left-adjust the Framed text when no Bullet/Arrow is rendered, since this was deemed to look better in the Framed context (especially when considering that CollapsingHeader is drawn using NoTreePushOnOpen, so child/sibling Text items etc will often be non-indented).

- TreeNode: Added ImGuiTreeNodeFlags_SpanFullWidth flag. This extends the hit-box to both the left-most and

right-most edge of the working area, bypassing indentation.

- Style: Allow style.WindowMenuButtonPosition to be set to ImGuiDir_None to hide the collapse button. (#2634, #2639)
