accounts/abi: implement new fallback functions (#20764)
* accounts/abi: implement new fackball functions In Solidity v0.6.0, the original fallback is separated into two different sub types: fallback and receive. This PR addes the support for parsing new format abi and the relevant abigen functionalities. * accounts/abi: fix unit tests * accounts/abi: minor fixes * accounts/abi, mobile: support jave binding * accounts/abi: address marius's comment * accounts/abi: Work around the uin64 conversion issue Co-authored-by: Guillaume Ballet <gballet@gmail.com>
