fix Swift compiler assert

Summary:
Asserts toolchains are crashing on compiling this header:
```
(struct_type decl="ObjectiveC.(file).ObjCBool")
(type_alias_type decl="ExecuTorch.(file).BoolValue@buck-out/v2/gen/fbsource/b60f3548330a4950/xplat/executorch/extension/apple/__ExecuTorch__/ExecuTorch_symlink_tree/ExecuTorch/ExecuTorchValue.h:37:14"
  (underlying=struct_type decl="Swift.(file).Bool"))
swift-frontend: /data/sandcastle/boxes/trunk-grepo-llvm-c2-grepo/external/swift/lib/ClangImporter/ImportType.cpp:928: ImportResult (anonymous namespace)::SwiftTypeConverter::VisitTypedefType(const clang::TypedefType *): Assertion `underlyingResult.AbstractType->isEqual(mappedType) && "typedef without special typedef kind was mapped " "differently from its underlying type?"' failed.
```
Remove `NS_SWIFT_BRIDGED_TYPEDEF` to mitigate.
