Bump to P27, CAP-0071 XDR, and add feature for xdr

[sisuresh]

What

This PR bumps env to p27, and adapts to the new xdr framework with ifdefs (https://github.com/stellar/pod-fsr/issues/12). It doesn't actually implement CAP-0071.

Not sure why, but CodeQL is failing on existing test code.

Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Updates the Soroban environment to protocol 27/28 metadata and aligns the codebase with the newer stellar-xdr framework, adding feature flags needed for CAP-0071/XDR-related experimentation and refreshing golden “observation” fixtures.

Changes:

• Add numerous protocol-27 observation JSON fixtures for dispatch/crypto/address/bytes/budget tests.
• Adjust env metadata protocol versions (curr → 27, next → 28) and update the xdr re-export approach.
• Add cap_0071 / test_feature feature plumbing and switch stellar-xdr workspace dependency to a pinned git revision.
