Shared Handles (#1619)

Browse Source 
* stage 1: added shared handles and all traits

* moved deleter to the shared part, now Shared handle weights 2 pointers

* Fixed Destroy Function

* generated headers

* At least no errors.

TODO: get image overload of shared handle back
make an example

* fixed all SFINAE issues, moved image specialization

* Added a sample

* made better example, added specialization for swapchain, added shared handles to readme

* Major update:
Fixed all wishes
Made std::shared_ptr do heavy lifting
Reduced code complexity
Added ParentType to basic handles
Added put and put_native for cross-abi usage

* more readme

* safer release()
removed put() for now

* better synchronization
inspired by STL shared_ptr implementation

* removed test shared pointer

* added forward type for better interop with VMA
added parent checking

* fixed getParent()

* added non-deleting overloads for Queue, DisplayKHR and PhysicalDevice

* Shared non-destoyed type now have handles

* using constructors are made to comply standard

* fixed leak

* shared handles migrated to own header,
made module entries

* header is independent now

* rebased repo, updated the example

* fixed most of the stuff

* renamed parent of, added guide to make shared handles

* vulkansc

* moved destructor to shared handle traits

* resolved issues with CI

* more relaxed memory ordering for release operation

* trying to remove submodule

* renamed to destructorType

* suppressed function cast warning

* only GCC should be affected

@ -436,6 +436,70 @@ For each function which constructs a Vulkan handle of type `vk::Type` Vulkan-Hpp
Note that using `vk::UniqueHandle` comes at a cost since most deleters have to store the `vk::AllocationCallbacks` and parent handle used for construction because they are required for automatic destruction.
### SharedHandle
Vulkan-Hpp provides a `vk::SharedHandle<Type>` interface. For each Vulkan handle type `vk::Type` there is a shared handle `vk::SharedType` which will delete the underlying Vulkan resource upon destruction, e.g. `vk::SharedBuffer` is the shared handle for `vk::Buffer`.
Unlike UniqueHandle, SharedHandle takes shared ownership of the resource as well as its parent. This means that parent handle will not be destroyed until all child resources are deleted. This is useful for resources that are shared between multiple threads or objects.
This mechanism ensures correct destruction order even if the parent SharedHandle is destroyed before its child handle. Otherwise, the handle behaves like `std::shared_ptr`. `vk::SharedInstance` or any of its child object should be last to delete (first created, first in class declaration)
There are no functions which return a `vk::SharedHandle` directly yet. Instead, you can construct a `vk::SharedHandle` from a `vk::Handle`:
```c++
vk::Buffer buffer = device.createBuffer(...);
vk::SharedBuffer sharedBuffer(buffer, device); // sharedBuffer now owns the buffer
```
There are several specializations of `vk::SharedHandle` for different handle types. For example, `vk::SharedImage` may take an additional argument to specify if the image is owned by swapchain:
```c++
vk::Image image = swapchain.getImages(...)[0]; // get the first image from the swapchain
vk::SharedImage sharedImage(image, device, SwapChainOwns::yes); // sharedImage now owns the image, but won't destroy it
```
There is also a specialization for `vk::SwapchainKHR` which takes an additional argument to specify a surface:
```c++
vk::SwapchainKHR swapchain = device.createSwapchainKHR(...);
vk::SharedSwapchainKHR sharedSwapchain(swapchain, device, surface); // sharedSwapchain now owns the swapchain and surface
```
You can create a `vk::SharedHandle` overload for your own handle type or own shared handles by providing several template arguments to SharedHandleBase:
- A handle type
- A parent handle type or a header structure, that contains parent
- A class itself for CRTP
With this, provide a custom static destruction function `internalDestroy`, that takes in a parent handle and a handle to destroy. Don't forget to add a friend declaration for the base class.
```c++
// Example of a custom shared device, that takes in an instance as a parent
class shared_handle<VkDevice> : public vk::SharedHandleBase<VkDevice, vk::SharedInstance, shared_handle<VkDevice>>
{
using base = vk::SharedHandleBase<VkDevice, vk::SharedInstance, shared_handle<VkDevice>>;
friend base;
public:
shared_handle() = default;
explicit shared_handle(VkDevice handle, vk::SharedInstance parent) noexcept
: base(handle, std::move(parent)) {}
const auto& getParent() const noexcept {
return getHeader();
}
protected:
static void internalDestroy(const vk::SharedInstance& /*control*/, VkDevice handle) noexcept {
vkDestroyDevice(handle);
}
};
```
The API will be extended to provide creation functions in the future.
### Custom allocators
Sometimes it is required to use `std::vector` with custom allocators. Vulkan-Hpp supports vectors with custom allocators as input for `vk::ArrayProxy` and for functions which do return a vector. For the latter case, add your favorite custom allocator as template argument to the function call like this:
