Adding optional exported function declaration string to bytecode modules. (#15782)

This allows iree-dump-module (and in the future other things) to report
the original source declaration for an exported function. This is only
intended to aid debugging and not machine interpretation.

Example from iree-dump-module:
```
Exported Functions:
  [  0] predict(!vm.ref<?>) -> (!vm.ref<?>)
        iree.abi.declaration: sync func @predict(%input0: tensor<1x28x28x1xf32>) -> (%output0: tensor<1x10xf32>)
```

Example from iree-run-module with invalid args:
```
D:\Dev\iree\runtime\src\iree\vm\invocation.c:95: INVALID_ARGUMENT; input list and function mismatch; expected 1 arguments but passed 0; invoking function 'predict'; `sync func @predict(%input0: tensor<1x28x28x1xf32>) -> (%output0: tensor<1x10xf32>)`
```

Frontends can attach an `iree.abi.declaration` attribute to public
functions to override the automatically generated string or add
`iree.abi.name` attributes to args/results to have them used instead of
the defaults.
