[Discussion] Investigate AOT Support

**Is your feature request related to a problem? Please describe.**

We don't currently support AOT with Brighter. As ever, there are trade-offs. AOT gives simple deployment and fast start-up at the cost of slower execution speed (JIT will be faster in the long run). It may be more useful in some scenarios than others. It potentially also adds to code complexity, we rely on lot on late-binding. Using code generation instead creates code that is harder to maintain than reflection-based code. For example whilst AOT helps with cold start for AWS Lambda we are rarely deployed within Lambda.

So we need to understand the value of AOT in scenarios we are deployed into, not just be "on trend".

This reminds me a bit of the "modern dotnet code is async fallacy", async trades execution speed for throughput, hence we support both.

**Describe the solution you'd like**
We need to start with a clear analysis of what we would need to change. We can then look at what we need to do to fix AOT issues and decide on the trade-offs. We also need to understand why folks want AOT.

**Describe alternatives you've considered**
The main alternative is to ignore AOT as irrelevant to our scenarios
