A shader reported in review binds 40 sampled images of one class, more
than 32. The cap only bounds the compact heap arrays, so no layout or
ABI version changes. The test covers 40 images and a full class through
the constant.

A compute program of PPSA26344 binds 29 sampled images of one class, more
than the 16 a typed sampled heap held, and failed with "shader image heap
capacity exceeded". Heap arrays are declared with their compact length,
so shaders that fitted before keep their layout and SPIR-V.
Bindless image tables keep 16 slots: they were sized by the same constant,
and each slot costs an image entry.

A typed storage-image heap held four elements, and a dynamic-mip storage
image takes four of them for its mip slots. A shader with a dynamic-mip
storage image and any other storage image of the same class needed five
and failed with "shader image heap capacity exceeded". The mip slots
per dynamic image stay four (StorageMipSlots); a storage heap now holds
sixteen elements (StorageHeapCapacity). Heap arrays are declared with
their compact length, so shaders that fitted before are unchanged.
