fix(rsc): remove server style when css import is removed

[hi-ogawa]

Description

• Closes remove server style when css import is removed #844

This allows removing stylesheet link via hmr but it turned out adding that back via <link /> in server component is not working likely because React tries to avoid re-inserting the same link.

Hmm, it looks like we already intentionally avoid adding ?t= to link href.

vite-plugin-react/packages/plugin-rsc/src/plugin.ts

Lines 1918 to 1921 in 5f9aec4

	// this doesn't include ?t= query so that RSC <link /> won't keep adding styles.
	const hrefs = [...cssIds].map((id) =>
	normalizeViteImportAnalysisUrl(environment, id),
	)

Created a new issue for now #850

TODO

• test with import.meta.hot
• test with fix(hmr): trigger prune event when import is removed from non hmr module vite#20768
• learn React float deduping mechanism
