minidump: Use the crashpad::internal namespace more appropriately

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.

LGTM. I was thinking this when you sent the StringListWriter.

Shoulda said something, I didn’t realize I had goofed on this until after it was
checked in.
