This lazily does an "npm install" when any package name matches what's
found in the package.json or when running a script from package.json
with deno task.
Part of #17916
Closes #17928
This commit enables resolution of "bare specifiers" (eg. "import express
from 'express';") if a "package.json" file is discovered.
It's a step towards being able to run projects authored for Node.js
without any changes.
With this commit we are able to successfully run Vite projects without
any changes to the user code.

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.

This commits adds auto-discovery of "package.json" file when running
"deno run" and "deno task" subcommands. In case of "deno run" the
"package.json" is being looked up starting from the directory of the
script that is being run, stopping early if "deno.json(c)" file is found
(ie. FS tree won't be traversed "up" from "deno.json").
When "package.json" is discovered the "--node-modules-dir" flag is
implied, leading to creation of local "node_modules/" directory - we
did that, because most tools relying on "package.json" will expect
"node_modules/" directory to be present (eg. Vite). Additionally
"dependencies" and "devDependencies" specified in the "package.json"
are downloaded on startup.
This is a stepping stone to supporting bare specifier imports, but
the actual integration will be done in a follow up commit.

Previously `jsxImportSource` was resolved relative to the config file
during graph building, and relative to the emitted module during
runtime.
This is now fixed so that the JSX import source is resolved relative to
the module both during graph building and at runtime.
