Subject: [PATCH 1/2] [libc++] Add a CI job for the LLDB data formatters

This patch adds a CI job running the LLDB data formatters in the libc++
CI. This should avoid breaking the LLDB data formatters when e.g. the
layout of libc++ data structures is changed.

This was originally opened as https://reviews.llvm.org/D133621.
