rpc: optimize tx index lookup (#810)

- emit tx index to cosmos events
- rpc side try to use the events, but fallback to heavier approach when fails.

Update rpc/ethereum/namespaces/eth/api.go

changelog

fix lint

# Events
The `x/evm` module emits the Cosmos SDK events after a state execution. The EVM module emits events of the relevant transaction fields, as well as the transaction logs (ethereum events).
## MsgEthereumTx
| Type | Attribute Key | Attribute Value |
| ----------- | ------------------ | ----------------------- |
| ethereum_tx | `"amount"` | `{amount}` |
| ethereum_tx | `"recipient"` | `{hex_address}` |
| ethereum_tx | `"contract"` | `{hex_address}` |
| ethereum_tx | `"txHash"` | `{tendermint_hex_hash}` |
| ethereum_tx | `"ethereumTxHash"` | `{hex_hash}` |
| ethereum_tx | `"txIndex"` | `{tx_index}` |
| tx_log | `"txLog"` | `{tx_log}` |
| message | `"sender"` | `{eth_address}` |
| message | `"action"` | `"ethereum"` |
| message | `"module"` | `"evm"` |
Additionally, the EVM module emits an event during `EndBlock` for the filter query block bloom.
