Fix memory leak at AssemblyLoadContext unload (#69334)

I have found there was a small memory leak when unloading
AssemblyLoadContext. A customer had a quite extreme testing case that
ran millions of iterations of creating an AssemblyLoadContext, loading
some assemblies into it and then unloading it. After 80 million
iterations on their machine with 8GB memory, the testing app was getting
out of memory.

Using PerfView, I was able to locate the source of the leak. It was a
missing destruction of the Module::m_pJitInlinerTrackingMap.
