feat(ssr): include non-CSS assets in the manifest

[ferdinando-ferreira]

Description

Include non-CSS assets in the ssr manifest, as planned in the following TODO:

vite/packages/vite/src/node/ssr/ssrManifestPlugin.ts

Lines 15 to 30 in b6d12f7

	if (chunk.type === 'chunk' && !chunk.isEntry) {
	// links for entry chunks are already generated in static HTML
	// so we only need to record info for non-entry chunks
	// TODO: also include non-CSS assets
	const cssFiles = chunkToEmittedCssFileMap.get(chunk)
	for (const id in chunk.modules) {
	const mappedChunks = ssrManifest[id] || (ssrManifest[id] = [])
	mappedChunks.push(base + chunk.fileName)
	if (cssFiles) {
	cssFiles.forEach((file) => {
	mappedChunks.push(base + file)
	})
	}
	}
	}
	}

Additional context

Also adds tests to the ssr-vue example. A font was included in the App.vue SFC to highlight the need to include entries in the manifest in the case of assets embedded in modules belonging to said entries.
