feat(free-layout): vertical line render support, line uiState remove "vertical" and add "shrink" "curvature" "style" "className" "strokeWidth" etc (#656)

* feat(free-layout): vertical line support and remove line vertical uiState

* feat(free-layout): line uiState add shrink and curvature

* refactor(free-layout): workflow-line-entity remove isDefaultLine

* chore: free-lines-plugin script

* refactor: fold-line

* refactor: remove manhattan line

* feat(free-layout-demo-simple): add switch line type

* feat(free-layout): workflow-line-entity uiState add className style strokeWidth

* refactor: remove FlowRenderKey.CONTEXT_MENU_POPOVER

* Revert "refactor: remove FlowRenderKey.CONTEXT_MENU_POPOVER"

This reverts commit e34234b79a23f3da17bce8b23491f93734fc0bb0.

* style: add deprecated to FlowRenderKey.CONTEXT_MENU_POPOVER
