  [llvm] Fix forward declaration in Support/JSON.h

Some methods of json::Array require json::Value to be completely defined, so
they can't be defined in-class. Fix that by defining them out of class.

Fix #55780

  Log Message:
  -----------
  [sanitizer] Don't call dlerror() after swift_demangle lookup through dlsym

Because the call to `dlerror()` may actually want to print something, which turns into a deadlock
as showcased in #49223.

Instead rely on further call to dlsym to clear `dlerror` internal state if they
need to check the return status.
