Mostly it's about Go 1.22+ syntax with ranging over integers, but it also
prefers ranging over slices where possible (it makes code a little better to
read).
Notice that we have a number of dangerous loops where slices are mutated
during loop execution, many of these can't be converted since we need proper
length evalutation at every iteration.

"Compare" is almost a standard one now, although math/big uses Cmp for historic
reasons (keys.PublicKey does so too). This also fixes Fixed8 since int64 to int
conversion is lossy.

It is used a lot in clients (including our benchmark).
`Uint160` is already optimized.
```
name old time/op new time/op delta
Uint256DecodeStringLE-8 150ns ±15% 112ns ± 3% -25.23% (p=0.000 n=10+10)
name old alloc/op new alloc/op delta
Uint256DecodeStringLE-8 96.0B ± 0% 64.0B ± 0% -33.33% (p=0.000 n=10+10)
name old allocs/op new allocs/op delta

We have a lot of native contract types that are converted to stack items
before serialization, then deserialized as stack items and converted back to
regular structures. stackitem.Convertible allows to remove a lot of repetitive
io.Serializable code.
This also introduces to/from converter in testserdes which unfortunately
required to change util tests to avoid circular references.
Frequently one needs to check if struct serializes/deserializes
properly. This commit implements helpers for such cases including:
1. JSON
2. io.Serializable interface
* deleted transfer_output added asset type and transaction result to core
* removed writing 0x00 when buffer length is 0
* Refactored emit into VM package + moved tx to own package.
* implemented transaction along with claimTransaction.
* refactored naming of transaction + added decode address for uint160 types
* removed unnecessary folder and files.
* transaction/smartcontract logic
* bumped version 0.24.0
* Initial draft of the neo-go wallet
* Cleanup + more test for util package
* integrated wallet into neo-cli partially
* base wallet implementation + smartcontract code.
