Support non-deterministic codecs via PayloadOptions

[ciricc]

Motivation

protojson.Marshal does not guarantee deterministic output (map key ordering, etc.),
causing panics during replay when payload comparisons fail.

Changes

• Added VmOptions to internal proto
• Modified Rust WASM binding to pass NonDeterministicChecksOption::PayloadChecksDisabled
• Added WithDisablePayloadChecks() method to server.Restate

Usage

restate := server.NewRestate().
WithDisablePayloadChecks().
Bind(...)

Fixes #116

Hey @ciricc, I think there was a misunderstanding in our initial discussion.

As said here: #116 (comment)
I think the checks should be disabled automatically on individual sys_ calls using protojson ser/de, and not on CoreVM::new. I also disagree that we should have a public API like WithDisablePayloadChecks(), as this opens up the doors for being misused...

Changes

• Added PayloadOptions message to internal proto with unstable_serialization field
• Modified syscall wrappers to pass PayloadOptions based on codec characteristics
• Added IsUnstableSerialization() function to detect non-deterministic codecs
• Added UnstableSerializer interface for custom codecs to declare instability
• ProtoJSONCodec is automatically detected as unstable

Added test suite for E2E testing (without changing the sdk-test-suite).

Just some minor bits, and it looks good!
