This is the kind that is used in Go (actually CGo) for exporting functions. I think it's best to use //export instead of our custom //go:export pragma, for consistency (they are equivalent in TinyGo). Therefore I've updated all instances to the standard format (except for two that are updated in https://github.com/tinygo-org/tinygo/pull/1024). No smoke tests changed (when comparing the output hash), except for some wasm tests that include DWARF debug info and tend to be flaky anyway.
