9c52b177ea [lldb][test] Add test for looking up decls in Clang modules for C++ 
Adds coverage for the code-path where
`ClangExpressionDeclMap::FindExternalVisibleDecls` finds a decl inside
of a Clang module (without explicitly having to import the module on the
LLDB CLI). AFAICT, we had not tests for this.

`LookupFunction` will try to find a `FunctionDecl` in debug-info. But if
no debug-info exists, it will ask the `ClangModulesDeclVendor` to search
for the function with the specified name in any of the Clang modules
that got added to it in `SetupDeclVendor`.
