[fidl][hlcpp] Fix bug in flexible union move constructor

This CL fixes a bug in HLCPP's move constructor for flexible unions. It
was only copying the unknown_data_.bytes rather than the entire
unknown_data_, leaving the handles field uninitialized. This manifested
as a misaligned pointer crash in the union's destructor.

Test: fx test fidl-hlcpp-conformance-test
