* Enable thread statics for collectible classes
This change removes checks that were preventing usage of thread statics
in collectible classes and also implements all the necessary changes.
The handles that hold arrays with thread statics are allocated from
LoaderAllocator for collectible classes instead of using the global
strong handle like in the case of non-collectible classes.
The change very much mimics what is done for regular statics.
This change also adds ability to reuse freed handles to the
LoaderAllocator handle table. Freed handle indexes are stored into a
stack and when a new handle allocation is requested, the indices from
this stack are used first.
Due to the code path from which the FreeTLM that in turn frees the
handles is called, I had to modify the critical section flags and also
refactor the handle allocation so that the actual managed array
representing the handle table is allocated out of the critical section.
When I was touching the code, I have also moved the code that was
dealing with handles that are not stored in the LoaderAllocator handle
tables out of the critical section, since there is no point in having it
inside of it.

* Remove AppDomain unload
This change removes all code in AppDomain that's related to AppDomain
unloading which is obsolete in CoreCLR. It also removes all calls to the
removed methods.
In few places, I have made the change simpler by taking into account the
fact that there is always just one AppDomain.

Enable assembly unloading
* Allow PInvoke methods on collectible assemblies
* Fix test unloadability
Several hundreds of tests were using Helper class that created
GCHandle, but never freed it. That prevented unloading of those
tests. The change modifies the Helper class to keep the handle
in a finalizable object.
Several GCHandle related tests were not freeing the GCHandle they
allocated, so this change adds freeing them to enable the unloading.
* Add missing error messages to the resources
* Fix shuffle thunk cache for unloadability
* Add GetLoaderAllocator to ICLRPrivBinder

This option was used for UMEntryThunkCode::Poison. Now we use own free list
to store freed thunks and don't return allocated memory to the LoaderHeap.
So reused thunks are always uninitialized.
