[vector_graphics] Initial import (#7941)

Imports https://github.com/dnfield/vector_graphics into this repository,
with history, and updates it to follow repository conventions:
- Adds missing licence headers.
- Removes analysis options and fixes resulting warnings.
- Updates min SDKs.
- Autoformats.
- Updates pubspecs to follow repo standard, including updating the
metadata
  to point to the Flutter repositories.
- Allows `xml` as a pinned dependency, and relaxes the pinning
requirement
  in the repo tools to allow an explicit, inclusive-endpoint range.
- Skips some unit tests on unsupported platforms.
- Adds repo metadata.
- Bumps versions and slightly relax version constraints to allow the new
  versions.

+# vector_graphics
+
+A vector graphics rendering runtime for Flutter. This package is intended for
+use with output from the `package:vector_graphics_compiler` and encoded via
+a tightly coupled version of `package:vector_graphics_codec`.
+
+## Commemoration
+
+This package was originally authored by
+[Dan Field](https://github.com/dnfield) and has been forked here
+from [dnfield/vector_graphics](https://github.com/dnfield/vector_graphics).
+Dan was a member of the Flutter team at Google from 2018 until his death
+in 2024. Dan’s impact and contributions to Flutter were immeasurable, and we
