Andy Shaw b274f656b8 Be able to create a response file for other generators too
When building an application for Android on Windows it is possible that
the command line will be too long when doing the link step. So the code
for generating a response file is moved to MakefileGenerator so it can
be used by the other generators easily. The same variables used by
MinGW can be used elsewhere then.

Fixes: QTBUG-71940
