assert: Avoid empty macros

common: uuid: Add hex string to UUID constructor

applet_swkbd: Include the null terminator in the buffer size calculation

hex_util: Fix incorrect array size in AsArray

Some games may interpret the read string as a null-terminated string instead of just reading the string up to buffer_size.

Although this isn't used, this is a potential bug as HexStringToArray will perform an out-of-bounds read.

config: Read connected setting for controllers

Currently yuzu will read the mapping but does not connect a controller
despite adding subsequent configurations for it. Read the `connected`
setting for now as a boolean like the Qt frontend.

This allows for easily converting a hex string into a Common::UUID, which is backed by a 128 bit unsigned integer.

config: Only read/write current_user on global config

network: fix ternary operator in Socket::SendTo

This makes UnswizzleTexture up to two times faster. It is the main bottleneck in NVDEC video decoding.

Makes the default game list folder icons 48x48 by default instead of 64x64, and allows for selecting small (24x24) and large (72x72) icon sizes.

service: set: Correct copy amount in GetAvailableLanguageCodes

 renderer_vulkan: Implement screenshots

vk_rasterizer: Flip viewport on Y_NEGATE

cmake, ci: Build bundled FFmpeg with yuzu

hle: api_version: Update HOS version to 12.1.0

Keeps us up to date with reporting the system version.

service: ns, set: Add PT_BR (Brazilian Portuguese)

emu_window: Remove global system instance

renderer_vulkan: Add setting to log pipeline statistics

applet_swkbd: Correct string buffer size calculation

It was just the one in emu_window_sdl2, but since _gl and _vk inherit
from it, they all needed adjustments.

Leaves just the one auto system& in main().

The buffer size here does not include the initial 8 bytes.

shader: Fold UnpackFloat2x16 and PackFloat2x16

shader: Fold integer FMA from Nvidia's pattern 

Simplifies the code a bit when possible. These instructions should be
no-ops codegen wise.

service: ns: Map ZH_TW and ZH_CN to Traditional/Simplified Chinese

common: uuid: Return a lower-case hex string in Format

Matches OpenGL's behavior. I don't believe this register flips geometry,
but we have to try to match behavior on both backends.
