vulkan_device: avoid attempt to access empty optional

opengl: Sanitize antialiasing config

video_core/vulkan: Fixed loading of Vulkan driver pipeline cache

The header size of the Vulkan driver pipeline cache files was incorrectly in PipelineCache::LoadVulkanPipelineCache, for which the pipeline cache wasn't read correctly and got invalidated on each load.

Port over several shader-compiler fixes from skyline

externals: update dynarmic, xbyak

net: Silently translate ETIMEDOUT network error

vulkan: implement 'turbo mode' clock booster 

VideoCore: Implement Cached Writes, use fastmem for reading GPU memory and eliminate old stuffs

MacroHLE: eliminate 2 rushed macros.

renderer_vulkan: implement fallback path for null buffer descriptors

vulkan_common: unify VK_EXT_debug_utils and selection of validation layer

The existing implementation only supports 64 invoc-per-subgroup GPUs, and misbehaves on adreno when invocations need to be split into 4 emulated subgroups.

Reuses most of the existing code for generating the gl_Layer passthrough. Fixes geometry in Nier: Automata on GPUs without HW passthrough support.

We can take advantage of SSBO addresses being passed in a constant bufer to account for the extra alignment requirements in the shader itself.

Adreno drivers will crash compiling geometry shaders if the input position is not wrapped in a gl_in struct.

video_core/vulkan: Implemented `VkPipelineCache` to store Vulkan pipelines

So that old cache can get deleted when the cache version changes and does not grow infinitely

The addition of the use_vulkan_driver_pipeline_cache option into the default ini string literal caused the 16,384-byte limit of the MSVC compiler to be exceeded.

As an optional feature which can be enabled in the advanced graphics configuration, all pipelines that get built at the initial shader loading are stored in a VkPipelineCache object and are dumped to the disk.

These vendor specific pipeline cache files are located at `/shader/GAME_ID/vulkan_pipelines.bin`. This feature was mainly added because of an issue with the AMD driver (see yuzu-emu#8507) causing invalidation of the cache files the driver builds automatically.
