[SM][iOS] CL 1/n: Refactor BlindSignAuth to accept generic attestation data (v2)

- Refactor BlindSignAuth to accept google::protobuf::Any for attestation data to enable cross-platform compatibility.

- Please Note: This is v2 of the CL. The original CL (cl/934771494) was rolled back because it broke postsubmit compilation for `pricli` targets (under //security/oak/tools/pricli). The breakage occurred because `pricli` was still using the old V1 callback signature (expecting absl::Span<const std::string>) while the CL refactored it to expect google::protobuf::Any.

- This v2 CL fixes the breakage by updating `pricli` (token_fetcher.cc and BUILD) to wrap its attestation data in `google::protobuf::StringValue` and pack it into the `Any` proto, resolving the compilation mismatch.

- Tested and verified that all pricli and BlindSignAuth tests pass:
