fix: only upload functions declared in config.toml

Bug fix

What is the current behavior?

1. If a function dir with index.ts is present on disk but not defined in config.toml, it is still deployed. I assume this isn't expected behavior.
   To Reproduce:

   • run: supabase functions new should-not-upload
   • comment out/remove this function's config from config.toml
   • run: supabase functions deploy --use-api
   • function is still deployed.
   

2. deploy success msg is shown for all function slugs, even the ones which aren't deployed. Also the slugs slice contains duplicates, so does the msg derived from slugs slice

   should-not-upload is disabled functions.should-not-upload.enabled=false but the deploy success msg still prints this slug and msg contains duplicates.
   

What is the new behavior?

• dont upload functions if not defined in config.toml. <function>.enabled behavior remains same.
• dedup slugs returned from GetFunctionSlugs and only print deploy success msg for functions actually deployed.

I think loop iteration can be skipped here.

if !ok {
			function.Enabled = false
			function.VerifyJWT = true
     		functionConfig[name] = function
     		continue
		}
