fix: reduce getSingleTrueBit() calls

[twoeths]

Motivation

• getSingleTrueBit() is called during attestation validation and in opPool while it is not simple:

getSingleTrueBit(): number | null {
    let index: number | null = null;

    const bytes = this.uint8Array;

    // Iterate over each byte of bits
    for (let iByte = 0, byteLen = bytes.length; iByte < byteLen; iByte++) {
      // If it's exactly zero, there won't be any indexes, continue early
      if (bytes[iByte] === 0) {
        continue;
      }

      // Get the precomputed boolean array for this byte
      const booleansInByte = getUint8ByteToBitBooleanArray(bytes[iByte]);
      // For each bit in the byte check participation and add to indexesSelected array
      for (let iBit = 0; iBit < 8; iBit++) {
        if (booleansInByte[iBit] === true) {
          if (index !== null) {
            // ERROR_MORE_THAN_ONE_BIT_SET
            return null;
          }

          index = iByte * 8 + iBit;
        }
      }
    }

    if (index === null) {
      // ERROR_NO_BIT_SET
      return null;
    } else {
      return index;
    }
  }

Description

• cache participationIndex as a result of attestation validation, so we don't have to extract it inside opPool
