As part of WT-11244 we found that MSan was returning false positives for tests that used external compressor libraries (snappy, zlib, etc) because while WiredTiger was compiled with MSan instrumentation the external libraries were not. This resulted in MSan reporting unsafe memory access that were in fact safe.

This ticket is to review all other external libraries that WiredTiger may (optionally) depend on, determine if they are useful to run in MSan testing, and if so ensure we provide MSan-instrumented versions of those libraries on the testing platforms.

This ticket is intended only for investigation and spinning off new tickets as needed. There should be no code deliveries against it.
