  -----------
  [SPIRV] Emit RuntimeDescriptorArrayEXT capability for all unbounded array types (#222819)

Previously, the `RuntimeDescriptorArrayEXT` capability was emitted only
for image descriptor arrays. This change emits the capability for the
shader whenever resource array has `ArraySize == 0`.

This covers all supported runtime descriptor array types, including
images, structured buffers, samplers, and counter descriptor arrays.
Emitting the capability for these arrays is necessary to support dynamic
resources in SPIR-V.
