This uses a ring buffer similar to OpenGL's stream buffer for small
uploads. This stops us from allocating several small buffers, reducing
memory fragmentation and cache locality.
It uses dedicated allocations when possible.
Report device enumeration errors with exceptions to be consistent with
other initialization related function calls. Reduces the amount of code
to maintain.
Initialize debug callbacks (messenger) from a separate file. This allows
sharing code with different backends.
Change our Vulkan error handling to use exceptions instead of error
codes, simplifying the initialization process.
