Support gRPC status for versions >=1.40

[damemi]

The Status fields for gRPC have changed several times. Since we only recently added support for parsing the gRPC status into auto-instrumentation, I think it is reasonable to add a gate to only support the Status for recent versions (that have the same field format), rather than adding various checks for every version of gRPC.

Working on testing this manually

Fixes #1225

Can you add a changelog mentioning the fix and what support restrictions this introduces?

I was able to manually test this with a grpc example and realized the error was coming from earlier than my first commits, so I switched to using StructFieldConstMinVersion (thanks @RonFed! forgot we had that)

Writing down my repro steps:

Tested by cloning https://github.com/grpc/grpc-go/tree/v1.39.x and building an image with this Dockerfile:

FROM golang:latest

RUN mkdir -p /app

WORKDIR /app

COPY . .

ENV GOPATH /app

RUN cd examples/helloworld/greeter_client && go install .
RUN cd examples/helloworld/greeter_server && go install .

Then loaded that image into a kind cluster and created this pod (along with a jaeger service):

apiVersion: v1
kind: Pod
metadata:
  name: grpc
spec:
  shareProcessNamespace: true
  containers:
  - name: grpc-server
    image: grpc-test
    imagePullPolicy: Never
    command: ['/app/bin/greeter_server']
    ports:
    - containerPort: 3000
  - name: auto-instrumentation
    image: otel-go-instrumentation
    imagePullPolicy: Never
    securityContext:
      runAsUser: 0
      privileged: true
    env:
      - name: OTEL_GO_AUTO_TARGET_EXE
        value: /app/bin/greeter_server
      - name: OTEL_EXPORTER_OTLP_ENDPOINT
        value: "http://jaeger:4318"
      - name: OTEL_SERVICE_NAME
        value: "grpc"

Without 6fa573c, I got the same error from the auto-instrumentation pod as reported in #1225 (comment). After adding that commit, it seems to work:
