gl_rasterizer: Implement RASTERIZE_ENABLE

gl_shader_cache: Style changes

vk_resource_manager: Catch device losses and other changes

Texture Cache: Add HLE methods for building 3D textures

vk_shader_decompiler: Misc changes

This commit adds a series of HLE methods for handling 3D textures in
general. This helps games that generate 3D textures on every frame and
may reduce loading times for certain games.

renderer_vulkan/shader: Add helper GLSL shaders

vk_shader_decompiler: Use Visit instead of reimplementing it

shader/memory: Implement LDG.U8 and unaligned U8 loads

Remove false commentary. Not dividing by 4 the size of shared memory is
not a hack; it describes the number of integers, not bytes.

While we are at it sort the generated code to put preprocessor lines on
the top.

ExprCondCode visit implements the generic Visit. Use this instead of
that one.

As an intended side effect this fixes unwritten memory usages in cases
when a negation of a condition code is used.

shader/conversion: Implement byte selector in I2F

shader/texture: Properly shrink unused entries in size mismatches

Notify the programmer when a request to release a fence is invalid
because the fence is already free.

This allows us to put VKFenceWatch inside a std::vector without storing
it in heap. On move we have to signal the fences where the new protected
resource is, adding some overhead.

VK_NV_device_diagnostic_checkpoints allows us to push data to a Vulkan
queue and then query it even after a device loss. This allows us to push
the current pipeline object and see what was the call that killed the
device.

When full decompilation was enabled, labels were not being inserted and
instructions were misused. Fix these bugs.

Avoid changing gl_Position when the NDC used by the game is [0, 1]
(Vulkan's native).

Some games write from fragment shaders to an unexistant framebuffer
attachment or they don't write to one when it exists in the framebuffer.
Fix this by skipping writes or adding zeroes.

gl_shader_decompiler: Add missing DeclareImages

shader_bytecode: Fix TLD4S encoding

vk_scheduler: Delegate commands to a worker thread and state track

RASTERIZE_ENABLE is the opposite of GL_RASTERIZER_DISCARD. Implement it
naturally using this.

NVN games expect rasterize to be enabled by default, reflect that in our
initial GPU state.

LDG can load single bytes instead of full integers or packs of integers.
These have the advantage of loading bytes that are not aligned to 4
bytes.

To emulate these this commit gets the byte being referenced (by doing
"address & 3" and then using that to extract the byte from the loaded
integer:

result = bitfieldExtract(loaded_integer, (address % 4) * 8, 8)

I2F's byte selector is used to choose what bytes to convert to float.
e.g. if the input is 0xaabbccdd and the selector is ".B3" it will
convert 0xaa. The default (when it's not shown in nvdisasm) is ".B0", in
that example the default would convert 0xdd to float.

When a image format mismatches we were inserting zeroes to the texture
itself. This was not handling cases were the mismatch uses less
coordinates than the guest shader code. Address that by resizing the
vector.

common: SPSCQueue: Notify after incrementing queue size.

These shaders are used to specify code that is not dynamically generated
in the Vulkan backend. Instead of packing it inside the build system,
it's manually built and copied to the C++ file to avoid adding
unnecessary build time dependencies.

quad_array should be dropped in the future since it can be emulated with
a memory pool generated from the CPU.
