common_funcs: Add enum flag bitwise shift operator overloads

Vulkan/Descriptors: Increase sets per pool on AMD propietary driver.

vk_rasterizer: Fix dynamic StencilOp updating when two faces are enabled

This adds bitwise shift operator overloads (<<, >>, <<=, >>=) in the macro DECLARE_ENUM_FLAG_OPERATORS(type)

FS: Mark recursive CreateDirectory as inaccurate and temporary

vk_state_tracker: Remove unused function

This function was incorrectly using the stencil_two_side_enable register when dynamically updating the StencilOp.

shaders: Fix warp instructions on 64-thread warp devices

account: EnsureTokenIdCacheAsync

FS: Recursively create directories for CreateDirectory

main: Apply confirm exit setting in exit locked scenarios

hid/am: Stub SetTouchScreenConfiguration and implement GetNotificationStorageChannelEvent

common: Move error handling functions out of common_funcs

api_version: Update and add AtmosphereTargetFirmware

Some titles set an exit lock through HLE, which prompts an exit confirmation when stopping emulation if the system is locked.
This change allows bypassing this confirmation if the setting to confirm exits has been disabled by the user.

This allows us to avoid implicitly including <string> every time common_funcs.h is included.

nvdec: Add GPU video decoding for all capable drivers and platforms

vk_rasterizer: Only clear depth/stencil buffers when specified in attachment aspect mask

vk_swapchain: Prefer linear swapchain format when presenting sRGB images

renderer_vulkan: Wait on present semaphore at queue submit

nvflinger: Use external surface format for framebuffer creation

renderer_vulkan: Spirv support glsl  legacy attribute
