Simon Binder be893fdf27 [vm/ffi] Add providesSymbol to DynamicLibrary 
This adds the providesSymbol method to DynamicLibrary. It returns
whether the library contains a function with the given name.

As per dlsym(3), it is valid for dlsym to return nullptr in a success
case if the symbol actually has a NULL value. So I've changed the logic
to check for dlerror() after we invoke dlsym(), both in the existing
lookup and in the new method.

Closes https://github.com/dart-lang/sdk/issues/46192
