Closes #19970
This commits adds logic to retry failed module downloads once.
Both request and server errors are handled and the retry is done after
50 ms wait time.
This changes npm specifiers to be handled by deno_graph and resolved to
an npm package name and version when the specifier is encountered. It
also slightly changes how npm specifier resolution occurs—previously it
would collect all the npm specifiers and resolve them all at once, but
now it resolves them on the fly as they are encountered in the module
graph.
