[HLSL] Fix resource wrapper declaration (#129100)
The resource wrapper should have internal linkage because it contains a handle to the global resource, and it not the actual global. Makeing this changed exposed that we were zeroinitializing the resouce, which is a problem. The handle cannot be zeroinitialized. This is changed to use poison instead. Fixes #122767. --------- Co-authored-by: Helena Kotas <[email protected]>
