This PR splits the decision making into two variables:

  1. browserSupportsCanvasKitChromium: This only takes effect in auto mode. If it's true, then we try to download the Chromium variant first, and fallback to the full variant. (This is currently still hardcoded to false so users don't get the Chromium variant just yet)

  2. canvasKitVariant: After CanvasKit is successfully downloaded, this variable contains the variant that was downloaded. This allows us to control what CanvasKit APIs to use depending on which CanvasKit variant we are using.

Required by #39984

Part of flutter/flutter#118801

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?
