fix(build): Explicitly build DLL target in Windows build script

The default `nmake` target for `libpg_query` builds the static library
and runs tests, but does not produce the required `pg_query.dll`.

This commit changes the build command to `nmake /F Makefile.msvc dll`
to specifically instruct the build system to create the dynamic link
library needed for the .NET application. This resolves the
"Build artifact pg_query.dll not found" error.
