Export the viteBuild command from @remix-run/dev/vite

[alessandrojcm]

Hi there, in my project I'd like to have a CLI that runs both the client and server build (we're using a custom server). Right now for Remix I am jus calling build() and build({ssr: true}) but as per #8211 that is not guaranteed to work with certain plugin configurations. As Remix's vite:build command is just calling viteBuild from remix-run/dev/vite/build, could that function be exported from the package so it could be used by consumers of the package? IMO is ok if it is undocumented and not subject to semver, I believe that it would fit nicely upon Remix's philosophy of giving dvelopers full flexiblity and it'll allow to write custom build scripts for people that have that use case. Thanks!
