  Build external interpreter program on demand (#24731)
  
  This patch teaches GHC how to build the external interpreter program
  when it is missing. As long as we have the `ghci` library, doing this is
  trivial so most of this patch is refactoring for doing it sanely.

  Mark T26410_ffi as fragile on Windows
  
  As seen in #26595, this test intermittently fails on Windows.
  This commit marks it as fragile, until we get around to fixing it.
