Subject: [PATCH] cmake: remove SDL_STATIC_VCRT option

projects are expected to use CMAKE_MSVC_RUNTIME_LIBRARY to select the
runtime library.

With current CMake versions, this can be done with:

 -DCMAKE_POLICY_DEFAULT_CMP0091=NEW -DCMAKE_MSVC_RUNTIME_LIBRARY=xxx

with xxx one of:
 "MultiThreaded"         -> -MT (static non-debug)
 "MultiThreadedDLL"      -> -MD (shared non-debug)
 "MultiThreadeDebug"     -> -MTd (static debug)
 "MultiThreadedDebugDLL" -> -MDd (shared debug)

See CMake documentation for more information:
https://cmake.org/cmake/help/latest/policy/CMP0091.html
https://cmake.org/cmake/help/latest/variable/CMAKE_MSVC_RUNTIME_LIBRARY.html
