support `nuxi dev --no-prepare`

[malkhuzayyim]

Describe the feature

I think the nuxi dev command should have the option of --skip-prepare, to allow users to explicitly skip running the prepare step as part of the initial run of dev.

This allows us to benefit from turborepo task dependency & caching to decrease the startup time in follow up runs for prepare if no files changed. This is especially useful in a monorepo setup with many nuxt apps.
