* p2w-attest: price batching

This commit introduces support for multiple Pyth product/price pairs
per call. The initial maximum batch size is 5 and is enforced using a
`P2W_MAX_BATCH_SIZE` constant.

solana/pyth2wormhole/program:
* On-chain batching logic
* Batch message parsing logic

solana/pyth2wormhole/client:
* Off-chain batching logic - divides any number of symbols into
largest possible batches
* Use a multi-symbol config file instead of CLI arguments

third_party/pyth/p2w-sdk:
* Expose batch parsing logic

third_party/pyth/p2w-relay:
* Comment out target chain calls until ETH contract supports batching
* Test the batch parsing function

third_party/pyth/p2w_autoattest.py:
* Generate and use the symbol config file  with pyth2wormhole-client

third_party/pyth/pyth_publisher.py:
* Add a configurable number of mock Pyth symbols
* Adjust HTTP endpoint for multiple symbols

* p2w-attest: mention attestation size in batch

This commit ensures that no matter the attestation format, a batch
will never contain attestations of different sizes. This guarantee
enables forward compatibility by adding new constant-size fields at
the end of a batch at all times. An older implementation will simply
not consume the remaining newer values while respecting the stated
batch member alignment.

* pyth2wormhole-client: use fresh blockhashes, harden batch errors

This commit makes sure we don't have to deal with expired transactions
due to stale blockhashes. The problem existed with larger symbol
configs as well as on Solana mainnet. Additionally, the attestation logic
now treats transaction errors as non-critical - a failure for a batch
does not prevent attestation attempts for batches farther in the queue
