Add EIP-1898 support needed for The Graph compatibility

Browse Source 
Fixes: #10814

This PR updates the following RPC methods according to EIP-1898
specs.

The following RPC methods are affected:

- eth_getBalance
- eth_getStorageAt
- eth_getTransactionCount
- eth_getCode
- eth_call

Note that eth_getBlockByNumber was not included in this list in
the spec although it seems it should be affected also?

Currently these methods all accept a blkParam string which can be
one of "latest", "earliest", "pending", or a block number (decimal
or hex). The spec enables caller to additionally specify a json
hash which can include the following fields:

- blockNumber EthUint64: A block number (decimal or hex) which is
  similar to the original use of the blkParam string
- blockHash EthHash: The block hash
- requireCanonical bool) If true we should make sure the block is
  in the canonical chain

Since the blkParam needs to support both being a number/string and
a json hash then this to properly work we need to introduce a new
struct with pointer fields to check if they exist. This is done
in the EthBlockParamByNumberOrHash struct which first tries to
unmarshal as a json hash (according to eip-1898) and then fallback
to unmarshal as string/number.
