Remove all the leftover instances in layer that still use the
generic allocator rather than the VkAllocationCallbacks
Add additional memory utility that allows to release memory
allocated by custom allocators using RAII

Document instance_private_data and device_private_data.
Add additional utility containers (util::unordered_set,
util::unordered_map) that ensure that the storage containers
we use allow the use of the Vulkan allocation callbacks.
Additionally, ensure that these allocations don't throw in
case host runs out of memory but rather return the appropriate
Vulkan error code.
Also keep a copy the allocators so they can be used in other layer
functionality to facilitate following the Vulkan specification around
memory allocation.
Add additional utility util::optional that currently makes it easier
to handle errors in the containers described above.
Fix some small issues with the vkCreateInstance/vkCreateDevice
handling and ensure that vkDestroyDevice is called in the layer
handler.

This utility will be used in future commits.
Also add -Wno-undefined to the linker flags to prevent leaving
undefined symbols in the layer .so file. Fix issues highlighted while
using this flag.

Change util::allocator's create and destroy methods so that they can
allocate multiple objects, in line with the allocate and deallocate
methods of std::allocator.
Also add documentation for util::allocator and its methods.
Finally, use util::allocator in swapchain.cpp, rather than allocating
memory directly via VkAllocationCallbacks.

Add util::vector to provide functionality similar to std::vector,
i.e. growable arrays. util::vector does its allocations via a custom
allocator provided via VkAllocationCallbacks and provides methods to
check whether the allocation fails, e.g. try_push_back() returns false
when the allocation fails and replaces std::vector's push_back() method
that would rather raise an exception to report an allocation failure.
Note that this commit switches on exceptions in the layer by removing
the flag -fno-exceptions.
util::vector is also used to store swapchain images.
