Fix require("prismjs") in webpack, Rspack, esbuild and Parcel bundles

[DmitrySharabin]

Compile import.meta.url to undefined in the CJS build, so dist/cjs no longer calls require("url").

Rollup's CJS output for import.meta.url calls require('u' + 'rl'), Node's url module. Browser bundlers resolve it even split like that. Rollup also put the core's resolveAlias into the same chunk, so require("prismjs") itself, not only the Autoloader, pulled in url.

require("prismjs") from an npm pack tarball of v2:

	Before	After
webpack 5.111, Rspack 2.2	Fails: Can't resolve 'url'	Builds
esbuild 0.28	Fails: Could not resolve "url"	Builds
Parcel 2.16	Fails: Failed to resolve 'url'	Builds
Vite 8.3	Module "url" has been externalized	Builds
Rollup 4.64, Bun 1.4	Builds	Builds

• Code that reads import.meta.url gets undefined in the CJS build. The Autoloader handles it and falls back to ./.
