Builder client (#10703)

Browse Source 
* builder api client

* unexport error

* thanks, DeepSource!

* replace hexSlice w/ hexutil.Bytes

* use uint256 for BaseFeePerGas

* more confidence in correct endianness

* comment fix per Terence

* fix proto conversion for uint256

* couple more value checks in the http client tests

* TestMarshalBlindedBeaconBlockBodyBellatrix

* appease deepsource

* middleware to log requests

* big int round trip test

* very superficial test to make deepsource happy

* round trip test between proto payloads

* round trip starting from marshaled struct

* deepsource... for you, the moon

* remove unused receiver

* gofmt

* remove test destroying line added while debugging

* handle nil body in logging middleware
