Subject: feat(info): Dependency count and sizes (#6786)

This commit changes "deno info" subcommand logic.

- Modules are no longer loaded into V8 isolate - analysis
  is done using ModuleGraph.
- Removed deno_core::Deps structure.
- Modules are no longer type-checked and transpiled -
  "compiled" file is shown only if it is already available.
- Added number of unique dependencies for root module.
- Changed tree output:
  - file size is shown next to the dependency
  - repeated dependencies are marked with "*"
  - used less spaces in prefix to save terminal width
