[K/N] Fix calls checker use-after-free in main thread deinit
...
Calls checker was trying to read thread state while unlocking mutex in
unregister thread function. At this point thread is already
unregistered and reference to current thread node is dangling.
To avoid this, we nullify this reference in advance, as its anyway
explicitly passed to unregister function, not read from global.

[K/N][Runtime] Separate thread registering and making it 'Runnable'
...
The new GC will require threads to suspend right after registering
if Stop-The-World is requested. This patch changes the initial
thread state to kNative and adds a separate state switch right
after thread registering. This switch suspends if it is necessary.

[K/N][New MM] Move ThreadStateGuard to the main Memory.h

Integrating the stdlib with the thread states machinery requires

access by moving these parts to the main Memory.h header.

Some of unit-tests for the C++ part of the stdlib will require

for a separate thread. This patch makes this helper available
for tests in the main runtime module by moving it to the main
ThreadSupport.hpp.
