Maxwell3D: Implement Depth Mode.

This commit finishes adding depth mode that was reverted before due to
other unresolved issues.

vk_shader_decompiler: Add tessellation and misc changes

Update Sirit and its usage in vk_shader_decompiler. Highlights:
- Implement tessellation shaders
- Implement geometry shaders
- Implement some missing features
- Use native half float instructions when available.

vk_device: Misc changes

- Setup more features and requirements.
- Improve logging for missing features.
- Collect telemetry parameters.
- Add queries for more image formats.
- Query push constants limits.
- Optionally enable some extensions.

maxwell_3d: Add tessellation state entries

externals: Update Vulkan-Headers

vk_swapchain: Add support for swapping sRGB

kernel: Remove unnecessary includes

Over the course of the changes to the kernel code, a few includes are no
longer necessary, particularly with the change over to std::shared_ptr
from Boost's intrusive_ptr.

We don't know until the game is running if it's using an sRGB color
space or not. Add support for hot-swapping swapchain surface formats.

CpuCore: Clear exclusive state after doing a run in dynarmic.

shader_bytecode: Remove corrupted character

Implement FLO & TXD Instructions on GPU Shaders

[EA source]: Ignore git-related files in cmake for early access tarballs

This fixes the early-access builds on Windows (tested on EA 58). Cmake
was previously looking for git-related files that were stripped out of
the early access builds and failing; check if those exist before reading
them.

This commit corrects an error in which a Core could remain with an
exclusive state after running, leaving space for possible race
conditions between changing cores.

Add missing CMakeLists.txt from root folder to source upload

Fixes #3190

telemetry_session: Report renderer backend

We only have OpenGL as an option for now. Hardcode the entry.

Texture_Cache: Redo invalid Surfaces handling.

kernel: Implement a more accurate IPC dispatch.

gl_framebuffer_cache: Optimize framebuffer cache management

texture_cache/surface_base: Fix out of bounds texture views

Some texture views were being created out of bounds (with more layers or
mipmaps than what the original texture has). This is because of a
miscalculation in mipmap bounding. end_layer and end_mipmap are out of
bounds (e.g. layer 6 in a cubemap), there's no need to add one more
there.

Fixes OpenGL errors and Vulkan crashes on Splatoon 2.

Pack color attachment enumerations into a single u32. To determine the
number of buffers, the highest color attachment with a shared pointer
that doesn't point to null is used.
