Add JSON.stringify API compatibility to Bun.TOML.stringify

Browse Source 
Support both JSON.stringify-style and object-style parameters:

JSON.stringify-style:
- Bun.TOML.stringify(obj, null, 2)        // number for spaces
- Bun.TOML.stringify(obj, null, '\t')     // string for indentation

Object-style (advanced options):
- Bun.TOML.stringify(obj, null, { inlineTables: true })

Updated TypeScript definitions to reflect the enhanced API with
proper union types and comprehensive examples.
