The gRPC service-config support from bazelbuild#29912 is now on master. It lets users lengthen the whole-call deadline for `ByteStream.Read` so large downloads can keep running while they make progress. A longer deadline also lets a stalled stream wait just as long, because a total RPC deadline cannot distinguish progress from inactivity. This adds `--remote_grpc_download_idle_timeout` as an independent inactivity limit for `ByteStream.Read`. It defaults to 60 seconds to match the existing HTTP remote-cache default; setting it to `0` disables it. When a read goes idle, Bazel cancels it and translates the timeout-owned `CANCELLED` closure to `DEADLINE_EXCEEDED` so the normal cache retrier can resume from the received offset. Other RPCs, including `ByteStream.Write`, `Execute`, and `WaitExecution`, are unaffected. Timeout tracking uses a monotonic deadline and at most one scheduled task per call. This avoids retaining a canceled task for every response and prevents a timer from canceling a read that has since made progress. Normal gRPC forwarding stays in `finally` blocks so timeout bookkeeping failures cannot suppress messages or callbacks. Tests cover: - the 60-second option default and exclusion of `ByteStream.Write`; - cancellation status and single-task scheduling as reads make progress; - request and response forwarding when timeout bookkeeping fails; and - an in-process `ByteStream` flow that sends a prefix, stalls, fires the timeout deterministically, and verifies that the retry resumes from the next offset. The interceptor currently applies only to `ByteStream.Read`. The download-specific option name leaves room to cover future server-streaming download RPCs such as [`SplitChunks`](bazelbuild/remote-apis#377) without implying that every remote stream should share this timeout. Closes bazelbuild#29916. PiperOrigin-RevId: 956359263 Change-Id: Id8ae7c6dbb172f1e7e799536193458d9cbfb8c0c (cherry picked from commit 6e27dd1)
