[SPARK-16021] Fill freed memory in test to help catch correctness bugs
## What changes were proposed in this pull request?
This patches `MemoryAllocator` to fill clean and freed memory with known byte values, similar to https://github.com/jemalloc/jemalloc/wiki/Use-Case:-Find-a-memory-corruption-bug . Memory filling is flag-enabled in test only by default.
## How was this patch tested?
Unit test that it's on in test.
