 Description   

Much like in SERVER-48280, we should stand up a minimal MSAN variant, but this time using WT.

We will attempt to minimize the number of system libraries used by the build by using the presence of --sanitize=memory to disable features that rely on system libraries for which MSAN doesn't have built-in interceptors.

We will use this to evaluate whether MSAN gives good signal for us, before endeavoring to build a more comprehensive solution, such as an instrumented userspace.
