[2/6] widl: Pass type attributes from write_array_tfs to write_array_element_type.

[Dmitry Timoshkov]

This allows to differentiate strings and write appropriate rpc type
(FC_C_C[W]STRING instead of FC_[W]CHAR).

This patch also limits write_array_tfs() to pass attributes to
write_array_element_type() only for strings and avoids unwanted
changes to other pointer types.
