Add CMakePresets.json to fix VS built-in CMake build directory

When Visual Studio opens CMakeLists.txt directly (Open Folder / CMake mode),
it defaults to out/build/<config>/ as the binary directory. This breaks the
OdbcFb.vcxproj include path (../../build/_deps/...) which expects 'build/'.

CMakePresets.json standardizes the binary directory to 'build/' across all
environments (command-line, Visual Studio, CLion, VS Code), so the .vcxproj
include path works without manual adjustments.

Also adds CMakeUserPresets.json to .gitignore for user-local overrides.
