Is your feature request related to a problem? Please describe.

The current vcpkg openUSD port does not support user-defined schemas or exporting Python bindings for custom schemas. This limitation prevents users from extending USD with their own schemas and makes it difficult to integrate custom schema functionality with Python.

Proposed solution

Please enhance the openUSD port to support:

• User-defined schemas
• Exporting Python language bindings for custom schemas
• Support for tools such as usdGenSchema

This would enable users to extend USD and integrate custom schemas with Python, increasing the flexibility and usability of the port.

Describe alternatives you've considered

Alternatives include manually building USD with Python bindings and custom schema support, but this is complex and defeats the purpose of using vcpkg for simple and reproducible builds.

Additional context

Thank you for considering these enhancements!
