compiler: align with current wasm types proposal https://github.com/golang/go/issues/66984 - Remove int and uint as allowed types in params, results, pointers, or struct fields - Only allow small integers in pointers, arrays, or struct fields - enforce structs.HostLayout usage per wasm types proposal https://github.com/golang/go/issues/66984 - require go1.23 for structs.HostLayout - use an interface to check if GoVersion() exists This permits TinyGo to compile with Go 1.21. - use goenv.Compare instead of WantGoVersion - testdata/wasmexport: use int32 instead of int - compiler/testdata: add structs.HostLayout - compiler/testdata: improve tests for structs.HostLayout
