[TD]Cosmetic function overhaul (#14216)

* [TD]Cosmetic geometry and tools update

- all cosmetics to store geometry in same form
- all cosmetics to survive scaling and rotation
- extension functions to survive scaling and rotation

* [TD]overhaul leader point storage and editing

- add py routine makeLeader(points)

* [TD]add leader conversion utility

* [TD]Set Leader RotateWithView default to true

* [TD]fix intersection vertex position

* [TD]add CosmeticEdge::makeLineFromCanonicalPoints

* [TD]fix 2 Extension tools

- positioning in DrawCosmeticCircle
- mishandling of points in execLineParallelPerpendicular

* [TD]Remove duplicate constexpr

* [TD]fix 2x Cosmetic arc tools

* [TD]refactor LineFormat out of Cosmetic

* [TD]move cosmetic appearance settings to LineFormat

* [TD]remove 2 unused methods

* [TD]apply format to blue line & circle tools
