 Move the ResponseFile module from haddock into base

 GHC and the build tools use "response files" to work around the limit
 on the length of command line arguments on Windows. Haddock's
 implementation of parsing response files (i.e escaping/unescaping the
 appropriate characters) seems complete, is well tested, and also
 closely matches the GCC version. This patch moves the relevant bits
 into `base` so that it's easier for other libraries to reuse it.

 Test Plan: make test TEST=T13896
