Rename Go module and bump version to v0.39.0 (#574)

Next step of #566 to re-satisfy #319:
- Rename and move majority of Go code to `go/` subdirectory, creating a
new module `github.com/open-telemetry/otel-arrow/go`
- Bump version to `v0.39.0`
- Temporarily disable `otelarrowcol` local `replaces` statement
- Required until OpenTelemetry-Collector-Contrib components use the new
module name
