Mark Mentovai 9386a054e2 minidump: Use the crashpad::internal namespace more appropriately.
MinidumpLocationDescriptorListWriter and MinidumpRVAListWriter are
implementation details and should be in the crashpad::internal
namespace.

MinidumpUTF16StringListWriter and MinidumpUTF8StringListWriter are
accessible to outside code and should not be in this namespace.
