gn: Add spelling suggestions for args.gn and --args.

Demo:
ERROR at build arg file (use "gn args <out_dir>" to edit):11:13: Build argument has no effect.
use_clang = true
            ^---
Did you mean "is_clang"?

The variable "use_clang" was set as a build argument
but never appeared in a declare_args() block in any buildfile.

To view all possible args, run "gn args --list <builddir>"
