[flip-patterns] Enable "records" and "patterns" experiment flags.

This turns on the flags for these two language features and makes
them generally accessible.

Doing so causes a number of tests to fail, but the failures are
approved and there are filed issues for them. Most of the
failures are minor or only affect code using the new language
features.

This CL:

- Enables the features in experimental_features.yaml.
- Re-generates all of the various files generated from that.
- Makes some analyzer and front end changes that this CL
  inherited from Paul's original CL flipping all of the 3.0
  feature flags. I don't know what these changes are about, but
  I assume they are necessary.
- Pins a couple of tests to 2.19 since they deliberately test
  behavior that is specific to 2.19. (For most test changes, I've
  landed them separately, but there are a couple of stragglers
  in this CL.)

This doesn't enable "class-modifiers" or "sealed-types" and doesn't
include the core lib changes related to those.
