[Content collections] Load content config with full Vite setup (#6092)

* feat: use vite dev server for content config

* refactor: improve export naming

* chore: update `sync` to spin up server

* refactor: run sync before build in cli

* fix: move sync call to build setup

* chore: clean up attachContent... types

* chore: remove unneeded comment

* chore: changeset

* fix: attachContentServerListeners in unit tests

* fix: allow forced contentDirExists

* chore: update schema signature

* fix: move content listeners to unit test

* chore remove contentDirExists flag; unused

* chore: stub weird unit test fix
