widl: Fix generation of the type format string for conformant-varying structures.

The conformance needs to be added on to the offset in the buffer so
set this before calling each the writer of each class of pointer
description in write_pointer_description.

Pass the passed in offsets to buffer and memory to
write_pointer_description_offsets in
write_varying_array_pointer_descriptions.
