This commit backports Mutex, BasicLockableAdaptor, and DiagnosticInfo to
v4.2. These pieces came in completely in various interleaved commits.

Diagnostics for Latches" epic.

Mutex:
- SERVER-41357
- SERVER-41362

- SERVER-42165
- SERVER-42895

Note that while this commit adds these pieces and integrates them into
the mongo-server codebase, it does not convert existing stdx::mutex
construction. It also does not include the updates to Interruptible that
were done as part of "Improved Diagnostics for Latches".
