What motivated this change? We have another copy at src\coreclr\nativeaot\Runtime.Base\src\System\RuntimeTypeHandle.cs that can be updated as well.
Also, while you are on it - could you please delete this comment
private IntPtr _value; to the top in that file?

What motivated this change?
I was looking at what stack traces do allocations and at some point I had doubts that stacks are correct. So I tried to look at optimized=false traces. It was mostly the same, in terms of allocating paths, except a few cases of boxing, that are otherwise optimized.
What surprised me is the wrapping/unwrapping of EETypePtr in the RuntimeTypeHandle - it was near the top. It looks like a common operation, so I "fixed" it to not clutter the profile.
This change is not required, since JIT can optimize this away, but I figured it is better if I keep "fixed" variant.

Also, it may be nice to rename _pEEType to _value so that it is in sync with the full implementation.
