Allow PathFigureCollection to string conversion via converter

[symbiogenesis]

This should be fairly self-explanatory. Allows path figures to be serialized as a string, using the SVG path syntax, not just deserialized.

I added a full round-trip test in the simple test and the ComplexPaths test.

When I tested with a full round-trip test in the ComplexPaths test, the round-trip strings aren't completely identical, but the visual results are exactly the same on each object. Which is the important part.
Possibly the output is following the SVG path syntax more strictly than some of the InlineData for the test.

Do you have an example?

I just updated the tests so that the complex tests can pass bi-directionally. It required making the InlineData conform to stricter standards.

But those standards are just needed to create a fully identical string for bi-directional testing purposes. The standard itself is more forgiving, but the ToString operation needs to pick one of the multiple valid ways to serialize the path.

Seems likely. I mainly think native MAUI vector usage via Shapes should get more love.

We should be able to directly translate SVG to real MAUI shapes, and back again, ideally.

I have been able to write code to translate SVG into MAUI graphics to some degree. It feels kind of within reach.
