RFR: 8360707: Globally enumerate all blobs, stubs and entries

[Andrew Dinn]

Use the blob, stub and entry declarations to generate a single global enumeration for all blobs, likewise for all stubs and all entries. Modify stub generators in shared runtime, c1 runtime, c2 runtime and stub generator subsystems and their clients to use those enumerations consistently.
