Explicit exports

[benjaminwinger]

This should fix the issue with the windows build failing due to too many symbols.

Instead of exporting all symbols, this only exports those which are explicitly marked as part of the exported API. We probably don't want to enable this except for on Windows for the moment, since the KUZU_API annotations weren't previously strictly enforced and may not be complete. But I've enabled it on linux for testing to try and catch things that should be exported. (Edit: now disabled)

I've included the change from #2107 to help test, as those can link against the shared library, unlike the tests. I think we probably in the long run should rewrite the API tests to link against the shared library so we can make sure all the APIs are accessible, but they currently use helper functions and classes which are private.

In addition to avoiding the error on Windows this will be helpful on all platforms eventually, as it should reduce the size of the shared library and speed up library loading.
On Linux there is a related issue where the dynamic library exports all the symbols from static libraries linked to it. It should be possible to avoid that using linker version files I think, but it's not a priority right now, and this issue doesn't appear to occur on windows.
