CVE-2023-24936: Check type is allowed when deserializing instance types that implements INullable

…LibraryImportGenerator

Adds a "paramName_lastIndexMarshalled" variable to generated code that tracks the index of the last element in a collection that was marshalled. Then in the cleanup stage, we only clean up to that index. This works for single dimensional arrays of non-blittable elements.

For multidimensional arrays, this will fully initialize higher order arrays to simplify the generated logic. It is possible to avoid this and can be considered in a future PR, if we observe users of multi-dimensional arrays observing performance issues.

… and enable delay load of version.dll

`coreclr` delay loads `version.dll` and adds a hook such that it loads from the system directory. In single-file, we lost this behaviour since it uses static library version of `coreclr`. This adds the same mechanism to single-file.
