This is the initial step for support of Solidity errors in contract bindings.
As of this change, errors can be decoded, but are not supported in
bindings yet.

Closes #23157

* tests/fuzzers/abi: added abi fuzzer

* accounts/abi: fixed issues found by fuzzing

* tests/fuzzers/abi: update fuzzers, added repro test

* tests/fuzzers/abi: renamed abi_fuzzer to abifuzzer

* tests/fuzzers/abi: updated abi fuzzer

* tests/fuzzers/abi: updated abi fuzzer

* accounts/abi: minor style fix

* go.mod: added go-fuzz dependency

* tests/fuzzers/abi: updated abi fuzzer

* tests/fuzzers/abi: make linter happy

* tests/fuzzers/abi: make linter happy

* tests/fuzzers/abi: comment out false positives

* accounts/abi: added getType func to Type struct

* accounts/abi: fixed tuple unpack

* accounts/abi: removed type.Type

* accounts/abi: added comment

* accounts/abi: removed unused types

* accounts/abi: removed superfluous declarations

* accounts/abi: typo

* accounts/abi: removed Kind from Type struct

* accounts/abi: removed unused code

* 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

* accounts/abi: reorganizing package and some notes and a quick correction of name.

Refactored the abi package parsing and type handling. Relying mostly on
package reflect as opposed to most of our own type reflection. Our own
type reflection is still used however for cases such as Bytes and
FixedBytes (abi: bytes•).

This also inclused several fixes for slice handling of arbitrary and
fixed size for all supported types.

This also further removes implicit type casting such as assigning,
for example `[2]T{} = []T{1}` will fail, however `[2]T{} == []T{1, 2}`
(notice assigning *slice* to fixed size *array*). Assigning arrays to
slices will always succeed if they are of the same element type.

Incidentally also fixes #2379
