Youre missing some files from the previous PR: - IPhysicalDevice.h (esp the external memory properties stuff)

Btw please decide on `XCB` vs `Xcb` in the class names and document that decision.

I'm currently rewriting the `future_t` and `AsyncQueueDispatcher` because of deadlock bugs. This will need to be brought in line with the changes later.

> Also i have not seen any mention of `ICPUSkeleton` in #376 Is this something obsolete? not fully developed yet

btw can you make `IAsset()` constructor protected?

Edit: Superceded by https://discord.com/channels/593902898015109131/1078226704092381194/1083069244650045600

We can also probably nuke ```cpp //! Checks if the object is either not dummy or dummy but in some cache for a purpose inline bool isInValidState() { return !isDummyObjectForCacheAliasing...

~~Also `restoreFromDummy_impl_call` needs to be templated on `class AssetT` cause otherwise its not doing anything useful for us.~~ ~~Btw it should be the responsibility of the `convertToDummy` and `restore` `_impl`...

btw did you make DXC compile on macOS?

Do we merge or not yet?
