Fix static treelite build flag

[fallintoplace]

Summary

• Allow --static-treelite through build.sh argument validation.
• Add static-treelite to the getopt long-option list so the existing handler can run.

• PARALLEL_LEVEL=1 ./build.sh --static-treelite --help | rg -- "--static-treelite"

📝 Walkthrough

Summary by CodeRabbit

• Bug Fixes

  • The --static-treelite build flag is now properly recognized and parsed, preventing failures during build option validation.

• Build System Enhancements

  • The static Treelite setting is now forwarded into the nvForest build configuration, keeping static builds consistent across components.

Walkthrough

The build script now recognizes --static-treelite, and the CMake nvForest dependency receives the corresponding static Treelite setting.

I ran ./build.sh --static-treelite and it ran successfully. (Note: For this to work, your Python env should not have Treelite installed, so that the build can build Treelite from the source.)

Glad to hear. Thank you.
