feat(fonts): getFontBuffer()

[florian-lefebvre]

Todo

• throw on client
• alternative parameters
• need getFontData() => fontData first, which depends on refactor(fonts): use runtime as entrypoint #15181

Changes

• We have APIs to allow using font data programmatically, which was mainly designed for advanced usage such as OG images
• However, getting the font better has always been clunky. It actually didn't work during prererendering
• This PR introduces a new getFontBuffer() function that get the buffer using a url from the result of getFontData()
• In SSR if getFontData() is used, a js file is created per buffer in the server output in addition to actual files in the client output. Not sure there's much we can do about it
• On the client, calling the function always throws

Testing

• New unit test
• Add ssr integrated tests
• Add integrated tests
