The motivation for this is that bounds computation ended up being a fairly slow part of the aiks canvas patch, as we were computing the bounds of things multiple times. While this may not make a huge difference without that patch, I do think there are places where we may compute the bounds of a path more than once. |

This shows a small improvement on the tessellation benchmarks: |

SkiaPerf also noted a measurable drop in CPU util: https://flutter-flutter-perf.skia.org/e/?begin=1693944748&end=1693976367&keys=X482a7810cfb443f67edcbab15e03f59b&num_commits=50&request_type=1&xbaroffset=36676 |

Now that Paths are externally immutable, we can compute the bounds once at construction. This also allows the Skia conversions to set the already computed bounds.
