Picks up cockroachdb/rocksdb#58. We found a corruption caused by multiple FAT32 files assigned the same block cache key prefix. We don't know the extent to which this problem affects other filesystems or other Windows file ID generation mechanisms. We decided to turn off the reliance on filesystem for generating cache keys on Windows. Instead we use randomization per table reader. This would cause a performance penalty for use cases that open multiple table readers per file, but I believe cockroach is not such a use case. Fixes cockroachdb#40918, fixes cockroachdb#40950. Release justification: Prevents corruption on some Windows filesystems Release note: None

This is a subset of #40993 suitable for 19.2 and backport to 19.1.

Picks up cockroachdb/rocksdb#58.
We found a corruption caused by multiple FAT32 files assigned the same
block cache key prefix. We don't know the extent to which this problem
affects other filesystems or other Windows file ID generation mechanisms.
We decided to turn off the reliance on filesystem for generating cache
keys on Windows. Instead we use randomization per table reader. This
would cause a performance penalty for use cases that open multiple table
readers per file, but I believe cockroach is not such a use case.
Fixes #40918, fixes #40950.
