  [clang][frontend] Make `CompilerInstance::FailedModules` thread-safe (#135473)

This PR makes some progress towards making it possible to create clones
of `CompilerInstance` that are independent of each other and can be used
in a multi-threaded setting. This PR tackles
`CompilerInstance::FailedModules`, makes it a value-type instead of a
mutable shared pointer, and adds explicit copies & moves where
appropriate.

Besides that change, this PR also turns two previously free functions
with internal linkage into member functions of `CompilerInstance`, which
makes it possible to reduce the public API of that class that relates to
`FailedModules`. This reduces some API churn that was necessary for each
new member of `CompilerInstance` that needs to be cloned.
