Log:
[lldb] Add log output for the support files we pass to the
CppModuleConfiguration
CppModuleConfiguration is the most likely point of failure when we have weird
setups where we fail to load a C++ module. With this logging it should be easier
to figure out why we can't find a valid configuration as the configuration only
depends on the list of file paths.
