Update API Extractor and improve type declaration config

Upgraded @microsoft/api-extractor and related dependencies to latest versions for improved API extraction. Enhanced Vite config to better control .d.ts emission, restricting output to library sources and excluding benchmarks. Removed default export of WebGLHelpers from webglplot.ts for cleaner exports.
