#include "VideoCommon/ShaderGenCommon.h"
VideoCommon: Make use of fmt outside of shader generators Migrates most of VideoCommon over to using fmt, with the exception being the shader generator code. The shader generators are quite large and have more corner cases to deal with in terms of conversion (shaders have braces in them, so we need to make sure to escape them). Because of the large amount of code that would need to be converted, the conversion of VideoCommon will be in two parts: - This change (which converts over the general case string formatting), - A follow up change that will specifically deal with converting over the shader generators.

VideoCommon/ShaderGenCommon: Make template functions regular functions These are only ever used with ShaderCode instances and nothing else. Given that, we can convert these helper functions to expect that type of object as an argument and remove the need for templates, improving compiler throughput a marginal amount, as the template instantiation process doesn't need to be performed. We can also move the definitions of these functions into the cpp file, which allows us to remove a few inclusions from the ShaderGenCommon header. This uncovered a few instances of indirect inclusions being relied upon in other source files. One other benefit is this allows changes to be made to the definitions of the functions without needing to recompile all translation units that make use of these functions, making change testing a little quicker. Moving the definitions into the cpp file also allows us to completely hide DefineOutputMember() from external view, given it's only ever used inside of GenerateVSOutputMembers().

Use custom isnan implementation to avoid HLSL optimizer issues This adjusts the NaN replacement logic introduced in #9928 to work around the HLSL compiler optimizing away calls to isnan, which caused that functionality to not work with ubershaders on D3D11 and D3D12 (it did work with specialized shaders, despite a warning being logged for both; that warning is also now gone). Note that the `D3DCOMPILE_IEEE_STRICTNESS` flag did not solve this issue, despite the warning suggesting that it might. Suggested by @kayru and @jamiehayes.

This uncovered a few instances of indirect inclusions being relied upon in other source files. One other benefit is this allows changes to be made to the definitions of the functions without needing to recompile all translation units that make use of these functions, making change testing a little quicker. Moving the definitions into the cpp file also allows us to completely hide DefineOutputMember() from external view, given it's only ever used inside of GenerateVSOutputMembers().

ShaderGenCommon: Rename WriteFmt() to Write() Now that we've converted all of the shader generators over to using fmt, we can drop the old Write() member function and perform a rename operation on the WriteFmt() to turn it into the new Write() function. All changes within this are the removal of a <cstdarg> header, since the previous printf-based Write() required it, and renaming. No functional changes are made at all.

VideoCommon/ShaderGenCommon: Make template functions regular functions These are only ever used with ShaderCode instances and nothing else. Given that, we can convert these helper functions to expect that type of object as an argument and remove the need for templates, improving compiler throughput a marginal amount, as the template instantiation process doesn't need to be performed. We can also move the definitions of these functions into the cpp file, which allows us to remove a few inclusions from the ShaderGenCommon header.
