Commit Message

core: throw IOException when ProxySelector returns null or empty list (#12793)

ProxySelector.select(URI) is contractually required to return a non-null, non-empty list. Some implementations violate this, which previously caused an opaque crash in ProxyDetectorImpl:

```
java.lang.IndexOutOfBoundsException: Index: 0
    at java.util.Collections$EmptyList.get
    at io.grpc.internal.ProxyDetectorImpl.detectProxy
```

Detect this case explicitly and throw an IOException naming the offending ProxySelector class, so a broken implementation can be identified and fixed by its author rather than silently worked around in every caller.
