mention --profile/--library-profiling/--executable-profiling in stack --help ?

[simonmichael]

Steps to reproduce

With stack 2.1.3, multiple commands seem to accept these flags, eg:

• stack build --profile ...
• stack exec --profile ...
• stack --profile hoogle ...

and indeed they do affect the exec command as well as the build command. I assume they are accepted by all commands though ignored by most (eg hoogle).

Expected

Expected to see these flags mentioned in stack --help. Or at least stack exec --help.

Actual

They are mentioned only in stack build --help.

This would help users know that they also need to use --profile with stack exec (#4863). Mentioning them in stack exec --help would be more effective for this.
