Use hexutil.Uint for blockCount parameter and oldestBlock result value in feeHistory method

[lightclient]

The current spec uses an Integer type for the blockCount parameter and OldestBlock result value. The schema for these values define them to be a hex string.

(h/t @ryanschneider for finding)

Note that this will be a breaking change from 1.10.5 which was released with the previous behavior. I'm definitely torn on that.

H!i Also note that the "oldestBlock" in the output is also not Hex

[rjl493456442]

Just nitpicks.
@zsfelfoldi Please also check it, especially in the spec the OldestBlock type is rpc.BlockNumber but I think hexutil.Big is better since it can always be resolved.

LGTM (after fixing a build failure in the tests)

[lightclient]

@zsfelfoldi doh thanks for fixing the test.
