fix(cli): Support deno.lock with only package.json present + fix DENO_FUTURE install interactions with lockfile (#23918)
Fixes #23571.

Previously, we required a `deno.json` to be present (or the `--lock`
flag) in order for us to resolve a `deno.lock` file. This meant that if
you were using deno in an npm-first project deno wouldn't use a
lockfile.

Additionally, while I was fixing that, I discovered there were a couple
bugs keeping the future `install` command from using a lockfile.

With this PR, `install` will actually resolve the lockfile (or create
one if not present), and update it if it's not up-to-date. This also
speeds up `deno install`, as we can use the lockfile to skip work during
npm resolution.
