WGSL: Runtime-sized arrays not in 'storage' address space are being generated

[aleino-nv]

Affected tests:

• tests/autodiff/diff-ptr-type-array.slang

Example output:

WGPU error: Error while parsing WGSL: :8:67 error: runtime-sized arrays can only be used in the <storage> address space
fn MyPtrType_accumulate_0( this_0 : MyPtrType_0,  this_buffer_0 : array<f32>,  idx_0 : u32,  value_0 : f32)
                                                                  ^^^^^^^^^^

:8:51 note: while instantiating parameter this_buffer_0
fn MyPtrType_accumulate_0( this_0 : MyPtrType_0,  this_buffer_0 : array<f32>,  idx_0 : u32,  value_0 : f32)
                                                  ^^^^^^^^^^^^^

May be array of runtime-sized array/buffer and therefore out of scope.
