Change field execution function generation to use IL emitting

[Horusiath]

Currently during so-called compilation phase we're generating execution function for each field of each GraphQL object - we do it quite naively to be honest. The idea is to replace current function generation mechnism (which uses plain old function cominators + System.Reflection in few places) to function bodies constructed through System.Reflection.Emit.

Cool idea! Would you like to help with that?

It sounds interesting, but I'm not sure I got the idea. Regarding performance improvements in general, we should of course always make at least a small cost-vs-benefit analysis of introducing it. Is our "naive" approach really that much of a performance issue that we would replace it by a potentially more cryptic implementation? What are the use cases?
Besides, this issue was created in the year 2016 and we are in 2024 right now and nothing has happened.
Is this issue (still) relevant?
