Install on windows fixes

[bjosv]

After running a temporary changed CI job (build.yaml, job windows)
that builds and installs but using: ninja -v all install and a matrix of CMAKE_BUILD_TYPE
the following changes were found.

1. The pdb file is not longer created for hiredis_static since #1054, so remove installation attempts of the file on build types Debug or RelWithDebInfo
2. Copy the solution in #1054 for hiredis_ssl_static

One observation is that the debug information is added to the static library indifferent of the build type, i.e even for Release builds. Previously the .pdb debug file were only installed when building with the CMake build type Debug or RelWithDebInfo.

@kristjanvalur I guess you know Windows best, is this the common way? or should it be changed to only include debug info in Debug/RelWithDebInfo builds? I think that CMake only adds debug flags in Linux when building for Debug/RelWithDebInfo (like the -g flag).

Hi, sorry for late reply.
The presence of debug info in the .lib file has nothing to do with what happens during final linking. During linking of a .dll or .exe a .pdb may be generated. The necessary data can be found in the .lib file, or ignored. This change only means that an extra sidecar file is not needed to be lugged around with the static lib if you want debug info in the final.

Thanks @kristjanvalur. This is fine with me.

With this PR we now make sure that both installed static libraries can provide debug info in the same way, indifferent of CMake's build type.
