If Qt is configured with -release or -debug we must set CMAKE_DEBUG_TYPE
or CMAKE_RELEASE_TYPE, but not both.
This was broken by 82a2c7df which fixed the issue for iOS
simulator_and_device builds.
We have the following situation for both relevant CONFIG values:
debug_and_release build_all
iOS simulator_and_device unset set
Windows -release set unset
Windows -debug-and-release set set
Trivia: On Windows, when configuring with -release (or -debug) then
the *feature* debug_and_release is not set.
The *CONFIG* *value* however, is unconditionally set in
msvc-desktop.conf.
