Run a statement directly with `cabal v2-repl --run "func"`

## Problem

Currently it's possible to run a statement with shell piping but this gives a noisy output:

```bash
$ cabal v2-repl <<< ':type zip'
[ 1 of 40] Compiling..
..
Ok, 40 modules loaded.
ghci> zip :: [a] -> [b] -> [(a, b)]
ghci> Leaving GHCi.

$ cabal v2-repl <<< ':type zip' | wc -l
48
```

(From https://stackoverflow.com/questions/58600068/how-can-i-run-a-ghci-statement-in-cabal-v2-repl-directly-from-command-line)

## Proposal

It would be great to have a `--run ` that produces a one line output.

This would be useful to test IO in certain cases. For example, to produce a SQL query and then run it:

```bash
$ cabal v2-repl --run "Module.produceQuery" | psql
```
