Do not add debug/release to QMAKE_CONFIG. Let module system enable them

This solved QTBUG-26111 in which qtjsbackend gets built with an
incomplete framework on Mac OSX. This was traced back to commit
6a6fd56e66 which moved QMAKE_CONFIG
values from .qmake.cache to mkspecs/qmodule.pri. Since qtjsbackend
contains config tests it creates its own .qmake.cache which was
previously masking this issue.

QMAKE_CONFIG incorrectly contained debug for debug_and_release builds
even though debug and release are already present in the CONFIG variable
in mkspecs/qconfig.pri. The changes to configure prevent CONFIG in
qmodule.pri from containing debug and release variables and ensure
that QT_CONFIG contains build_all and debug_and_release if appropriate.
Configure.app is also adjusted to match this behaviour.

The other part of the change is to qt_module_config.prf and
qt_plugin.prf. These changes take care of populating CONFIG with
the appropriate debug_and_release and build_all variables depending
upon what is present in QT_CONFIG. This ensures that the Qt modules
and plugins get built with the same configuration as qtbase.

The special handling for the qcocoa QPA plugin ensures that it is
built in release mode only to preserve the behaviour introduced by
commit 5603f94eaa.
