Prefast Fixes (#12952)
**Description**: Fixes these TSA issues (no actual bugs fixed, but just
changing code to make TSA happy)
To fix 1944982 and 1944973 I changed DeleteOnUnloadPtr to not use 'new'
and to just use placement new to go into a fixed buffer. This required
changing the rocm usage of it also (probably a separate TSA bug on that
one that I don't have)
1944982 Ryan Hill [prefast:Warning]: C26426 (in
onnxruntime/core/providers/cuda/tensor/cast_op.cc)
Global initializer calls a non-constexpr function 'operator new' (i.22).
1944973 Ryan Hill [prefast:Warning]: C26426 (in
onnxruntime/core/providers/cuda/cuda_execution_provider_info.cc)
Global initializer calls a non-constexpr function 'operator new' (i.22).
1944929 Ryan Hill [prefast:Warning]: C26436 (in
onnxruntime/core/providers/cuda/cuda_provider_factory.cc)
The type 'struct onnxruntime::ProviderInfo_CUDA_Impl' with a virtual
function needs either public virtual or protected non-virtual destructor
(c.35).
