constexpr: resign ourselves to gcc dropping void -> T support

kern: remove need for explicit reserved member in KAutoObject

kern: devirtualize KAutoObject::DynamicCast<>() ...

This is an optimization that saves the most common type of virtual call in the kernel (DynamicCast)
by storing class token as a member, rather than getting it via virtual call every time.

This does not currently cost any memory space on 64-bit targets, due to pre-existing padding space.

This optimization can be turned off via a compile-time flag for accuracy.
