  [orc-rt] Fix WrapperFunctionBuffer empty range construction (#209751)

orc_rt_CreateWrapperFunctionBufferFromRange(const char *, size_t) left
the constructed buffer's data member uninitialized when the size
argument was zero. This could result in the returned buffer having a
non-null data field and a zero size field, which is a (malformed)
out-of-band error value, not an empty buffer.

Update orc_rt_CreateWrapperFunctionBufferFromRange to zero-initialize
the data field so that the size == 0 case yields a correctly formed
empty buffer.
