Fix crash when exiting Dawn samples

This patch fixes a crash (nullptr access) when closing the window of
Dawn samples by manually destroying all WGPU objects in main()
function. Without this step `wireHelper` (in SampleUtils.cpp) will
always be destroyed before any WGPU objects in each sample file, so a
nullptr access will occur when any WGPU object is destroyed as at that
time `dawnProcSetProcs(nullptr)` has already been called in
`~WireHelper()`.
