feat(task): dependencies (#26467)
This commit adds support for "dependencies" in `deno task` subcommand:
```jsonc
{
    "tasks": {
        "build": "deno run -RW build.ts",
        "generate": "deno run -RW generate.ts",
        "serve": {
            "command": "deno run -RN server.ts",
            "dependencies": ["build", "generate"]
        }
    }
}
```
Executing `deno task serve` will first execute `build` and `generate`
tasks (in parallel) and once both complete the `serve` task will be executed.

Number of tasks run in parallel is equal to the no of cores on the
machine, and respects `DENO_JOBS` env var if one is specified.
