Update CMakeList for Windows build and CI test

Great work!

I had a different vector construction setup, then came across your feature for regular array index access. I scraped/refactored my version in https://github.com/zelang-dev/c-raii/tree/main/src/vector.c to use yours exclusively, memory usage cleanup is automatic though, RAII.

There are a few ideas to make c-vector more expandable, like adding an enum type field to vector_metadata_t, macro to set/get.
