This change updates the kcov implementation to use the new Go coverage interface provided by the `internal/coverage` package. The previous implementation relied on `coverdata.Blocks`, which is part of the older coverage tooling. The new implementation uses `runtime/coverage.WriteCounters` to get the raw coverage data and then decodes it using `decodecounter.NewDecoder`. This approach is aligned with the modern Go coverage infrastructure. This change requires a patched Go compiler that allows importing internal packages. This is a temporary measure until the golang team provides a public API. More details can be found here: golang/go#51430 Signed-off-by: AV <avagin@gmail.com>
