One of the changes in macios revealed a bug in which @new can be null
resulting in a NRE like the one that follows:

The change that exposed the bug is: dotnet/macios@d78aa67

The above exception is avoided by ensuring that nor old or @new are
null.

vtable setup fix for generic default interface methods in mono runtime (

mono#21422)

When processing the overrides from interface default methods we should
check if the interface class is a generic type definition first and
inflate with the interface class context.

Avoid an assert in ves_icall_RuntimeFieldInfo_SetValueInternal (mono#…

…21420)

When the field is byref but the value being passes in is not, throw an
ArgumentException. Without this change the call to
mono_object_handle_pin_unbox will assert and kill the process.

This can occur when de-serializing an object and the field types have
changed.

Add missing handle function enter/return macros (mono#21407)

The mono_field_static_get_value method uses a handle, but did not set up
enter/exit macros properly, so this handle was leaked.

Some code in Unity calls this embedding API method pretty often, which
can lead to the mark stack overflowing in the GC code.

[interp] Remove hack for nint/nfloat (mono#21395)

These structures are valuetypes, but their mint_type is a primitive. This means that a LDFLD applied on the type would have attempted to do a pointer dereference, because it saw that the current top of stack is not STACK_TYPE_VT. This was fixed in the past by passing the managed pointer to the valuetype rather than the valuetype itself, against the normal call convention, which lead to inconsistencies in the code.

This commit removes that hack and fixes the problem by ignoring LDFLD applied to nint/nfloat valuetypes in the first place.
