accounts/abi: added abi test cases, minor bug fixes (#20903)
* accounts/abi: added documentation * accounts/abi: reduced usage of arguments.LengthNonIndexed * accounts/abi: simplified reflection logic * accounts/abi: moved testjson data into global declaration * accounts/abi: removed duplicate test cases * accounts/abi: reworked abi tests * accounts/abi: added more tests for abi packing * accounts/abi/bind: refactored base tests * accounts/abi: run pack tests as subtests * accounts/abi: removed duplicate tests * accounts/abi: removed unnused arguments.LengthNonIndexed Due to refactors to the code, we do not need the arguments.LengthNonIndexed function anymore. You can still get the length by calling len(arguments.NonIndexed()) * accounts/abi: added type test * accounts/abi: modified unpack test to pack test * accounts/abi: length check on arrayTy * accounts/abi: test invalid abi * accounts/abi: fixed rebase error * accounts/abi: fixed rebase errors * accounts/abi: removed unused definition * accounts/abi: merged packing/unpacking tests * accounts/abi: fixed [][][32]bytes encoding * accounts/abi: added tuple test cases * accounts/abi: renamed getMockLog -> newMockLog * accounts/abi: removed duplicate test * accounts/abi: bools -> booleans
