gl_texture_cache: Minor fixes and style changes

format_lookup_table: Fix ZF32_X24S8 component types

vk_texture_cache: Implement generic texture cache on Vulkan

Component types for ZF32_X24S8 were using UNORM. Drivers will set FLOAT,
UINT, UNORM, UNORM; causing a format mismatch. This commit addresses
that.

maxwell_3d: Make dirty_pointers private

renderer_opengl/utils: Forward declare private structs 

Fix git version in scm_rev.cpp

This isn't used outside of the class itself, so we can make it private
for the time being.

Nothing from these headers are used, so they can be removed.

Keeps the definitions hidden and allows changes to the structs without
needing to recompile all users of classes containing said structs.

control_flow: Silence -Wreorder warning for CFGRebuildState

gl_shader_cache: Remove unused variables

Organizes the initializer list in the same order that the variables
would actually be initialized in.

GUI/configure: resize hotkeys action column to fit content

Given this isn't used, this can be removed entirely.

Avoids several reallocations of std::vector instances where applicable.

Eliminates a few unnecessary constructions of std::vectors.

shader_ir/memory: Implement u16 and u8 for STG and LDG

shader_ir/texture: Simplify AOFFI code

maxwell_to_vk: Implement GL_CLAMP hacking Nvidia's driver

core/kernel: Fix GetTotalPhysicalMemoryUsed.

It currently ignores PBO linearizations since these should be dropped as
soon as possible on OpenGL.

vk_compute_pass: Add compute passes to emulate missing Vulkan features

module._memory was already moved over to a new shared_ptr.
So code_memory_size was not increased at all.

This lowers the heap space and so saves a bit of memory, usually between 50 to 100 MB.

This fixes a regression of c0a01f3a

Comment hardcoded SPIR-V modules.

Nvidia's driver defaults invalid enumerations to GL_CLAMP. Vulkan
doesn't expose GL_CLAMP through its API, but we can hack it on Nvidia's
driver using the internal driver defaults.

Using the same technique we used for u8 on LDG, implement u16.

In the case of STG, load memory and insert the value we want to set
into it with bitfieldInsert. Then set that value.

This currently only supports quad arrays and u8 indices.

In the future we can remove quad arrays with a table written from the
CPU, but this was used to bootstrap the other passes helpers and it
was left in the code.

The blob code is generated from the "shaders/" directory. Read the
instructions there to know how to generate the SPIR-V.
