- Adds tracing to the `GetBlobsV1/V2/V3`
- Adds `blobs.requested` and `blobs.filled` attributes to
`GetBlobsV1/V2/V3` spans.
- Adds tracing to `BlobTxPool().GetBlobs()`
Adds a fast path for ExecutionPayloadEnvelope and BlobAndProofListV*
that bypasses encoding/json's reflection and re-validation, which are
expensive for large payloads with many blobs. Also hand-rolls the
jsonrpcMessage wire encoding in the RPC codec to avoid a second
re-validation pass when writing responses to the connection.
