Use VK_KHR_pipeline_executable_properties when enabled and available to
log statistics about the pipeline cache in a game.
For example, this is on Turing GPUs when generating a pipeline cache
from Super Smash Bros. Ultimate:
Average pipeline statistics
==========================================
Code size: 6433.167
Register count: 32.939
More advanced results could be presented, at the moment it's just an
average of all 3D and compute pipelines.
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.
Instead of using a two step initialization to report errors, initialize
the GPU renderer and rasterizer on the constructor and report errors
through std::runtime_error.
Report device enumeration errors with exceptions to be consistent with
other initialization related function calls. Reduces the amount of code
to maintain.
Move surface initialization code to a separate file. It's unlikely to
use this code outside of Vulkan, but keeping platform-specific code
(Win32, Xlib, Wayland) in its own translation unit keeps things cleaner.
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.
