Replace Go-js with Go-wasi

[tsahee]

What's working?

system tests, including stylus, in both jit and arbitrator mode

go version #remember to use 1.21

make test-go-deps
go test -tags stylustest -run TestProgram ./system_tests/...

make target/machines/latest/user_test.wasm
cd arbitrator
cargo test

What's not working?

ipfshelper - the library we use is out-of-date. I stubbed out enough of it to be able to run system tests, but things like make build / make lint will not work.

one-step-proofs - not done yet.

recommended order for reading

arbcompress/, wavmio/

These changes are required for go 1.21, even if staying with wasm-js

arbitrator/wasm-libraries/{brotli, host-io}

Equivalent changes in the wasm libs

arbos/programs

Updated API to execute stylus programs

arbitrator/prover/src/{machine, wavm}.rs

required modifications for supporting the stylus->go callbacks. OSP not ready here but should be simple considering we only ever need state of either first or last {value, frame} stack

arbitrator/prover/src/host.rs

funcs using these new opcodes

arbitrator/wasm-libs/{user-host, program-exec}

implementation from arbitrator side

arbitrator/jit

the jit implementation
