Add x/programs

This PR adds WebAssembly (WASM) based program support and examples to the HyperSDK.

Rational: Why have the host in Go?
While there are many performance reasons to choose Rust as the host. AvalancheGo and HyperSDK are in Go. While we are making strides in many areas of Rust in the ecosystem (IE firewood) it made sense for us to build this solution on top of the existing HyperSDK. This will allow for devs to build upon our existing and very performance focused HyperSDK.

Rational: Why have the guest in Rust?
Rust was chosen because of its amazing crypto community and much like WebAssembly itself Rust developers tend to enjoy lower level programming. We find that Rust provides efficient handling of bytes and compiles down to very efficient WebAssembly.

Rational: Why name this programs?
Because that is exactly what they are autonomous programs that live on chain. They technically are not all that smart and also not always a contracts. We hope that by using the term programs developers and non technical folks can more easily understand the term.

Performance: Initial benchmarks for the token program using metering shows ~16ms. More work is required to improve/understand overall performance.

Can you also post a benchmark without metering?

[patrick-ogrady]

You can fix the static issue by running go mod tidy in each example vm.

Can you also post a benchmark without metering?

yes will add a few more example tests and these benches as a followup.
