Multithreaded runtime builds on Windows /MT[d]

[heindl-solutions]

for the main project, there is OATPP_MSVC_LINK_STATIC_RUNTIME:BOOL=ON to switch to /MT build on Windows. This is missing for this subproject

I had to workaround using
cmake ... -DCMAKE_POLICY_DEFAULT_CMP0099=NEW -DCMAKE_MSVC_RUNTIME_LIBRARY="MultiThreaded$<$<CONFIG:Debug>:Debug>"

I think OATPP_MSVC_LINK_STATIC_RUNTIME should be added to oatpp-swagger and oatpp-sqlite as well to be consistent.

Thank you very much for the good work!
