Implement Response File support for HPC

This is an improvement to HPC authored by Richard Wallace
(https://github.com/purefn) and myself. I have received permission from
him to attempt to upstream it. This improvement was originally
implemented as a patch to HPC via input-output-hk/haskell.nix:
https://github.com/input-output-hk/haskell.nix/pull/1464



Paraphrasing Richard, HPC currently requires all inputs as command line arguments.
With large projects this can result in an argument list too long error.
I have only seen this error in Nix, but I assume it can occur is a plain Unix environment.

This MR adds the standard response file syntax support to HPC. For
example you can now pass a file to the command line which contains the
arguments.

```
hpc @response_file_1 @response_file_2 ...

The contents of a Response File must have this format:
COMMAND ...

example:
report my_library.tix --include=ModuleA --include=ModuleB
```

Updates hpc submodule
