cmake: always define `CURL::win32_winsock` on Windows in `curl-config.cmake`

The CMake config can be consumed by project which enable only language
`CXX`. `CMAKE_C_COMPILER_ID` isn't defined in this case, and the target
definition would be missing. But the check for compiler id isn't really
needed: The target is namespaced and valid, regardless of actual
compiler.

Noticed in https://github.com/microsoft/vcpkg/issues/49518, building cpr.

Follow-up to 16f073ef49f94412000218c9f6ad04e3fd7e4d01 #16973

Closes #20382
