tests: add BIP-352 test vectors

Add the BIP-352 test vectors. The vectors are generated with a Python script
that converts the .json file from the BIP to C code:

$ ./tools/tests_silentpayments_generate.py test_vectors.json > ./src/modules/silentpayments/vectors.h

The short version
What changed, and why it matters

This commit only adds test data and test infrastructure for the BIP-352 silent payments feature. It does not change any production cryptographic code, so it cannot introduce a runtime security vulnerability on its own.
Recommended action
No security action required; review the corresponding silent payments implementation separately if assessing that module.
Security signals we found

No strong security signals were identified.
Technical analysis
Evidence from the diff

The commit adds BIP-352 silent payment test vectors (a large JSON file plus a generated C header), a Python generator script, and build-system wiring to compile the new tests. No implementation logic in src/modules/silentpayments/main_impl.h or the public API is modified. The change is purely additive test coverage.
