This buffer was a list of EncodingData structures sorted by their bit length, with some duplication from the cpu decoder implementation.
We can take advantage of its sorted property to optimize its usage in the shader.

Thanks to wwylele for the optimization idea.

Moves leftover values that are no longer used by the gpu decoder back to the cpp implementation.

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

shader: Mark ConvertF16F32 and ConvertF32F16 as fp16 instructions

host_memory: enable fastmem on FreeBSD

general: Implement FullscreenMode enumeration 

applets/web: Addressing QT Navigation issues in Linux

cmake: unbreak libusb detection on FreeBSD

Fixes instances where fp16 types are not declared on SPIR-V but they are
used. This shouldn't happen on master, as it's been uncovered by an
additional optimization pass.

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.

render_target: Add missing initializer for size extent

common: fs: fs_util: Add BufferToUTF8String

src/common/host_memory.cpp:360:14: error: use of undeclared identifier
      'memfd_create'
        fd = memfd_create("HostMemory", 0);
             ^

HW.Memory <Critical> common/host_memory.cpp:HostMemory:492: Fastmem unavailable, falling back to VirtualBuffer for memory allocation

video_core/engine: Consistently initialize rasterizer pointers

exception: Make constructors explicit

video_core: Remove some unused variables

vulkan_wrapper: Fix SetObjectName() always indicating objects as images

Focusing on the first link element fixes element navigation upon loading the web applet in games such as Super Mario Odyssey

Everything else has a default constructor that does the straightforward
thing of initializing most members to a default value, except for the
size.

We explicitly initialize the size (and others, for consistency), to
prevent potential uninitialized reads from occurring. Particularly given
the largeish surface area that this struct is used in.
