This commit changes the default value of Fast Texture Sampling to true, and also moves the setting that controls it to the experimental section of the advanced tab. This is its own commit so that it can be easily reverted when we want to default to Manual Texture Sampling.

Specifically, when using Manual Texture Sampling, if textures sizes don't match the size the game specifies, things previously broke. That can happen with custom textures, and also with scaled EFB copies at non-native IRs. It breaks most obviously by not scaling the texture coordinates (so only part of the texture shows up), but the hardware wrapping functionality also assumes texture sizes are a power of 2 (or else it will behave weirdly in a way that matches how hardware behaves weirdly). The fix is to provide alternative texture wrapping logic when custom texture sizes are possible.
Note that both GLSL and HLSL provide a fwidth (fragment width) function defined as `fwidth(p) = abs(dFdx(p)) + abs(dFdy(p))`. However, it's easy enough to implement this ourselves (and it makes the code a bit more obvious).
The benefit to exposing this over the raw BP state is that adjustments Dolphin makes, such as LOD biases from arbitrary mipmap detection, will work properly.
This was added in 0b9a72a62d38481ff08f742b2318d07f29ff5dff but became irrelevant in 70f9fc4e7526fc9cfc008a43cd33229f62be99b6 as the check is now self-explanatory due to a rejiggering of the bitfields.
These messages apply to the User directory regardless of
whether it's global or local, so we shouldn't specify "global".
Also changing "directory" to "folder", just for consistency
with "GC folder" in the same sentence.
We implement this by first rounding to nearest integer using the current
rouding mode, then converting this value from floating point to an integral
value.
Prefer using eax to isolate the sign bit. This saves a byte when the
destination ends up as r8-15, because those require a REX prefix.
Before:
41 8B C5 mov eax,r13d
41 C1 ED 1F shr r13d,1Fh
44 03 E8 add r13d,eax
41 D1 FD sar r13d,1
After:
41 8B C5 mov eax,r13d
C1 E8 1F shr eax,1Fh
44 03 E8 add r13d,eax
41 D1 FD sar r13d,1
This function was deprecated in ffmpeg in January[1], while its
replacement got introduced in 2015[2], so now might be the time to start
using it in Dolphin. :)

This moves the only direct call to zlib’s crc32() into its own
translation unit, but that operation is cold enough that this won’t
matter in the slightest. crc32_z() would be more appropriate, but
Android has an older zlib version…
This was originally intended to fix https://bugs.dolphin-emu.org/issues/12717 but this ended up not being the issue (instead it seems like files just weren't recompiled when imgui was updated due to MSVC weirdness). Still, using brackets instead of quotes is preferable as this is a library include.
