### What problem does this PR solve?
Issue Number: close #25509
Related PR: #61248
Problem Summary: S3/OSS prefetch timeout can cancel and close
PrefetchBufferedReader while an async PrefetchBuffer task is still running. The
task kept PrefetchBuffer alive but only stored the underlying FileReader as a
raw pointer, so the owner could destroy the reader before the async task
resumed on the error path and logged reader metadata. Keep a shared FileReader
reference in each PrefetchBuffer so the async prefetch task cannot outlive the
reader it dereferences, and add a unit test that covers close timeout while the
prefetch read is blocked.

### Check List (For Author)
- Test: git diff --check; git diff --cached --check; attempted
build-support/clang-format.sh and build-support/check-format.sh but
llvm@16/clang-format is not installed; attempted ./run-be-ut.sh --run
buffered_reader_test but it failed before running tests because JAVA_HOME
points to JDK 11 and JDK_17 is not set
- Behavior changed: No
- Does this need documentation: No
