What does this PR do? Why is it needed?

We use go build for local development and bazel build for CI.
Our IDE has Analyze Stack Trace feature for navigation to code from log traces.

So, we want to have more IDE friendly logfile stack traces like:

3 @ 0x447bb6 0x457a3c 0xc0ee95 0xc0f5a5 0xc18d8a 0x479161
#	0xc0ee94	google.golang.org/grpc/internal/transport.(*controlBuffer).get+0x114	go/pkg/mod/google.golang.org/grpc@v1.47.0/internal/transport/controlbuf.go:408

instead of:

1 @ 0x438d96 0x448812 0xeb7155 0xeb7865 0xec0fc5 0x468e81
#	0xeb7154	google.golang.org/grpc/internal/transport.(*controlBuffer).get+0x114	external/org_golang_google_grpc/internal/transport/controlbuf.go:408

This PR allow customize stackpath prefix for go_repository rule like:

    go_repository(
        name = "org_golang_google_grpc",
        importpath = "google.golang.org/grpc",
        stackpath = "go/pkg/mod/google.golang.org/grpc@v1.47.0",
        sum = "h1:9n77onPX5F3qfFCqjy9dhn8PbNQsIKeVU04J9G7umt8=",
        version = "v1.47.0",
        ...
    )
