Summary:
Add backend options support to the ExecuTorch Swift/ObjC bindings.
The C++ Module class supports LoadBackendOptionsMap for passing per-delegate configuration (e.g. compute unit, thread count, cache directory) at model load time, but this was not exposed through the Swift/ObjC layer. This diff adds:
A new ExecuTorchBackendOption ObjC class (BackendOption in Swift) representing a single key-value configuration option with support for boolean, integer, and string value types.
New load and loadMethod overloads on ExecuTorchModule that accept a dictionary mapping backend identifiers to arrays of backend options.
Swift extensions providing idiomatic load(backendOptions:verification:) and load(_:backendOptions:) APIs on Module.
```
let module = Module(filePath: "model.pte")
try module.load(backendOptions: [
"CoreMLBackend": [
BackendOption("compute_unit", "cpu_and_gpu"),
BackendOption("num_threads", 4),
BackendOption("use_cache", true),
]
])
```
