Allow generation of multiple gems for Windows

- This allows build gems for both VC6 and MinGW builts of Ruby.

    Rake::ExtensionTask.new('my_extension', GEM_SPEC) do |ext|
      ext.cross_compile = true
      ext.cross_platform = ['i386-mswin32', 'i386-mingw32']
    end

This is highly experimental and exposed the need to refactor
ExtensionTask internals. Right now it fires the compilation
process twice, which is suboptimal.
