[BUG] [Parquet] Fix double-await on JoinHandles concurrency bug in Parquet reader.

[clarkzinzow]

This PR fixes a double-await concurrency bug on JoinHandles in the Parquet reader. The bug appears to arise when an a byte range fetch fails: we currently short-circuit that fetch and return an error to the stream mapper without changing the range cache state. This means that future fetches that overlap with that byte range will try to .await on the same JoinHandle, which is not allowed.

This PR fixes this by storing a Result<Bytes, Error> in RangeCacheState::Ready(), so we can stash errors from past fetches.

TODOs

• Validate on TPC-H Q1 benchmark reproduction.
• Ensure that PR matches at least the status quo in terms of fault-tolerance
