Similar to Webpack there's apparently other bundlers that will not leave `import`-calls alone unless magic comments are used. Hence we extend the builder to also append `/* @vite-ignore */` comments to `import`-calls, in order to attempt to improve support for using the PDF.js builds together with Vite. This patch also renames `__non_webpack_import__` to `__raw_import__` since the functionality is no longer bundler-specific. ***PLEASE NOTE:*** This patch is provided as-is, and it does *not* mean that the PDF.js project can/will provide official support for Vite.
