spirv/nir: add capability check for SpvCapabilityAtomicStorage

Browse Source 
Capability that informs if atomic counters are supported. From SPIR-V
1.0 spec, section 3.7, "Storage Class", item 10 from table:

(Column "Storage Class"):

   "AtomicCounter For holding atomic counters. Visible across all
    functions of the current invocation. Atomic counter-specific
    memory."

(Column "Required Capability"):

   "AtomicStorage"
