[lldb] Add a SymbolFileProvider to record and replay calls to dsymForUUID

When replaying a reproducer captured from a core file, we always use
dsymForUUID for the kernel binary. When enabled, we also use it to find
kexts. Since these files are already contained in the reproducer,
there's no reason to call out to an external tool. If the tool returns a
different result, e.g. because the dSYM got garbage collected, it will
break reproducer replay. The SymbolFileProvider solves the issue by
mapping UUIDs to module and symbol paths in the reproducer.
