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.

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.

Ensures all of the engines have consistent and deterministic
initialization of the rasterizer pointers.

We should be using the passed in object type instead.

Given this is non-trivial, the constructor is required to execute, so
this removes a bit of redundant codegen.

Resolves two compiler warnings.

Ensures that exception construction is always explicit.

We can use the <exception> header instead of pulling in all of the
exception-style classes.

Allows for direct conversion to std::string without having to convert std::u8string to std::string

general: Rename "Frame Limit" references to "Speed Limit"

vk_stream_buffer: Remove unused stream buffer
