Add victory-vendor package for d3 dependencies by @becca-bailey in https://github.com/FormidableLabs/victory/pull/2204

Vendor in d3 libraries to new package victory-vendor and upgrade. Our CommonJS path now uses transpiled versions of the d3-* libraries while our ESM path continues to use the real underlying dependencies.

• Update our tests to only refer to built versions of our libraries (in the past there was a mix of source and built). This means Karma uses the ESM version of libraries while Jest uses the CommonJS versions.
• Added very basic Node.js tests to catch future ESM issues.
• Switch all relative/prefixed import paths to be just import <name> from "victory-<pkg>".
• Update various dependencies.
