Subject: feat(compile): Enable multiple roots for a standalone module graph
 (#17663)

This change will enable dynamic imports and web workers to use modules
not reachable from the main module, by passing a list of extra side
module roots as options to `deno compile`.

This can be done by specifying "--include" flag that accepts a file path or a
URL. This flag can be specified multiple times, to include several modules.
The modules specified with "--include" flag, will be added to the produced
"eszip".
