CMake: Assign proper postfixes in multi-config builds
In a single-config build on Linux, we usually don't want a debug
postfix in library names (as opposed to Windows/macOS).
But when doing a multi-config build on Linux, assigning no postfixes
causes CMake to generate rules for a single config only, the first one
specified in CMAKE_CONFIGURATION_TYPES.
This leads to being unable to build all configurations from the same
build.ninja file as well as other obscure issues like race-conditions
when generating prl files.
To address this, when doing a multi-config build, always assign a
postfix for each config except the first release-like one, while
preserving the existing rules we had for debug postfix names.
Pick-to: 6.2 6.3
Fixes: QTBUG-100493
