feat(browser): Add View Hierarchy integration (#14981)

By default it captures the entire DOM, but it is configurable:

Capture only React components (uses attributes added by Sentry bundler
plugins):
```ts
import * as Sentry from '@sentry/browser';

Sentry.init({
  dsn: '__DSN__',
  integrations: [Sentry.viewHierarchyIntegration({
    onElement: ({componentName}) => componentName ? {} : 'children'
  })],
});
```

Capture only Web Components:
```ts
import * as Sentry from '@sentry/browser';

Sentry.init({
  dsn: '__DSN__',
  integrations: [Sentry.viewHierarchyIntegration({
    onElement: ({tagName}) => tagName.includes('-') ? {} : 'children'
  })],
});
```
