A vite port version of next.js optimizePackagesImports

why

Some packages exports lots of modules, it will cause vite transform lots of files in build step. For example, @mui/icons-material exports 1000+ components, it's harmful for vite build performance.

Test on Apple M1 Pro, with this plugin, it improve 50%+ build performance.

[!NOTE]
According to swc_compat_range_docs, you should select right @swc/core version.
