Feat: Use Deno 2 parallel server

[yooneskh]

Describe the feature

Deno 2 has landed and it introduced parallel server mechanism to allow using all of the cores of the CPU. Nitro can easily add support for that and allow all of the ecosystem to benefit from this.

Additional information

• Would you be willing to help implement this feature?

Vinxi is using nitro for build and server, and I think vinxi can't use Deno at all at the moment:

nksaraf/vinxi#407

I wonder if the missing piece to make things work is in nitro or vinxi, and if this will fix it too.
