Support constructed stylesheets in shadow DOM instances

[andrewortwein]

Detect, serialize, and rebuild constructed stylesheets in shadow DOM elements.

QA

1. Go to packages/rrweb-snapshot
2. Run yarn build
3. Run yarn link to set this package up for local linking
4. In the chromatic-e2e repo, use the locally-linked rrweb-snapshot build in the cypress, playwright, and shared packages by replacing "@chromaui/rrweb-snapshot": "2.0.0-alpha.17" with "@chromaui/rrweb-snapshot": "link:../../../rrweb/packages/rrweb-snapshot" in each package.json
5. Run yarn test:playwright && yarn archive-storybook:playwright to launch the built Storybook
6. Verify that the styles render in shadow DOM elements and styles render in web components in shadow DOM stories properly display the color styles that are described by the text on those story pages
7. Repeat steps 5 & 6 for cypress I tried this but Cypress didn't seem to like the local link, so we will need to verify this after we publish a version of this package

@andrewortwein so far this looks good! Let me know when you're ready for QA and I'll give it a go there as well.

@thafryer good point -- originally we were going to merge this PR and wait to do a proper release until my deduplicating-the-stylesheets work was in, but we've since decided the deduplicating work is not necessary right now.

@andrewortwein as part of this we'll want to release the NPM package as well, let me know if you want to pair on that.
