Port of dotnet/runtime#1059 to 3.1 branch (#27986)
This is the fix for #27924. This is a GC hole bug that was found externally, #27590.
The cause is that the JIT was using the target type of the subtract when it needed
to make a copy of the source, but it needs to use the source type.
## Customer Impact
Corruption of state that is non-deterministic and hard to track down.
## Regression?
Not a recent regression, but exposed by Unsafe.ByteOffset.
## Testing
The fix has been verified in the runtime repo.
## Risk
Low: The fix is straightfoward and only impacts 3 lines of code.
