layers: Special case VkWriteDescriptorSet safe_struct code

VkWriteDescriptorSet may have non-null ptrs that we don't care about.
Add a special case for this struct in safe_struct codegen that will only
check the array ptrs that we care about based on the descriptorType.

Also update safe_struct codegen so that all ptrs in structs are initially
set as NULL, and then only updated if src struct ptr is non-NULL.

Update unique_objects to base "if" guards around ptrs to be based off of
the shadowed safe_struct ptrs for any ptrs below the first level input
params. This is because safe_struct initialization will have already copied
down any ptrs so if there are any additional guards in safe_struct
shadowing, such as for VkWriteDescriptorSet, this allows unique_objects.cpp
to make use of only valid info and not have to replicate special cases.
