Avoid waiting for earlier submissions when we flush more often.
The vertex manager will flush more often if the game accesses the EFB
on the CPU, to give the GPU a head start.
Texture dumping can already be done using VideoCommon's system (and in fact the same setting already enabled *both* of these). Dumping objects/TEV stages/texture fetches doesn't currently have an equivalent, but could be added to the FIFO player instead.
Not doing so produces a warning in clang:
ISO C++20 considers use of overloaded operator '!=' (with operand types
'Metal::DepthStencilSelector' and 'Metal::DepthStencilSelector') to be
ambiguous despite there being a unique best viable function with
non-reversed arguments
The underlying reason for this warning is an incorrect method signature.
It stores both the konst selection value for alpha and color channels (for two tev stages per ksel), and half of a swap table row (there are 4 total swap tables, which can be used for swizzling the rasterized color and the texture color, and indices selecting which tables to use are stored per tev stage in the alpha combiner). Since these are indexed very differently, the old code was hard to follow.
The masking was incorrect. This affects the main menu of The Last Avatar, though that menu also relies on copy filter functionality that is not correctly handled in the software renderer so the difference is not obvious; that game shuffles textures across all indices for some reason, so this issue would presumably result in subtle flickering.
Per https://en.cppreference.com/w/cpp/preprocessor/replace#.23_and_.23.23_operators the `##` behavior is a nonstandard extension; this extension seems to be supported by all compilers we care about, but IntelliSense in visual studio doesn't correctly handle it, resulting in false errors in the IDE (but not when compiling).
Per https://en.cppreference.com/w/cpp/preprocessor/replace#Function-like_macros C++20 introduced a workaround, where `__VA_OPT__(, )` generates a comma if and only if `__VA_ARGS__` is non-empty.
This PR replaces all occurrences, with the exception of Externals, DSPSpy (which is not likely to be edited in MSVC and does not target C++20 currently), and JitArm64_Integer.cpp (which uses `Function(__VA_ARGS__)`, and thus does not ever need a comma).
