Devon Govett 694d3e1aae [Flight Parcel] Implement prepareDestinationForModule (#31799)
Followup to #31725

This implements `prepareDestinationForModule` in the Parcel Flight
client. On the Parcel side, the `<Resources>` component now only inserts
`<link>` elements for stylesheets (along with a bootstrap script when
needed), and React is responsible for inserting scripts. This ensures
that components that are conditionally dynamic imported during render
are also preloaded.

CSS must be added to the RSC tree using `<Resources>` to avoid FOUC.
This must be manually rendered in both the top-level page, and in any
component that is dynamic imported. It would be nice if there was a way
for React to automatically insert CSS as well, but unfortunately
`prepareDestinationForModule` only knows about client components and not
CSS for server components. Perhaps there could be a way we could
annotate components at code splitting boundaries with the resources they
need? More thoughts in this thread:
