20260212 3.7.5.r4504 (pre 3.7.6)

Fix: inaccurate ColorBarsHD 10+ bit values. Now they are derived from the 32-bit float
RGB definitions instead of upscaling a 8 bit precalculated YUV value.
Add Ramp section the lead-in-lead-out.
Fix: GreyScale + SSE2 + RGB32 + matrix="RGB" overflow.
Rare usage; "RGB" matrix (Identity) uses a 1.0 coefficient which exceeds the signed 16-bit
SIMD limit of 32767 at 15-bit precision. Added bounds checking to fallback to C-code for any
coefficients >= 1.0 or < −1.0.
Fix: YUV->RGB limited range matrix accuracy for 10-16 bits.
Use a different rounding in matrix coefficient's integer approximation.
"ConvertToPlanarRGB": bits parameter: on-the-fly bit-depth conversions to YUV->RGB conversion.
- Full range target: 8-16 bits internal calculation is in 32-bit float.
- Limited range target: a quicker, bit accuracy optimized integer calculation path.
Not Fixed: Speed degradation when in-constructor GetFrame(0) (e.g. frame-property getter)
is used. Disable internal Cache object creation. Does not work in complex scripts, preparation
is 5-10 min instead of <1 sec. Investigation continues (Issue AviSynth#476: AviSynth#476)
Avoid MTGuard and CacheGuard creation if filter returns one of its clip parameter unaltered.
Add some avx2 stuff to Layer and Invert
Optimization: Overlay "Blend": aarch64 NEON optimization

optimization: add AVX2 TurnLeft/TurnRight/Turn180 (R/L: 1,5-3x speed).
optimization: ConvertBits AVX2 integer->float
optimization: ConvertToPlanarRGB(A): YUV->RGB add AVX2 (2-3x speed)
optimization: ConvertToPlanarRGB(A): YUV->RGB 16 bit: a quicker way (1,5x)
Fix: C version of 32-bit ConvertToPlanarRGB YUV->RGB to not clamp output RGB values.
ConvertToPlanarRGB(A): add bits parameter to alter target bit-depth.
ConvertToPlanarRGB(A): from YUV->RGB full range output: optimized in-process when bits=32, other cases call ConvertBits internally.
Fix: Packed RGB conversions altering the bit-depth (e.g. rgb32->ConvertToRGB64() worked always in full range.
Add more AVX512 resampler code. (WIP)
Add more AVX512_BASE code paths (Resamplers)
Build: add _avx512b.cpp/hpp pattern in CMake to detect source to compile with base (F,CD,BW,DQ,VL) flags.
However AVX512_BASE itself is set only when AVX512_FAST found.
For pre-Ice Lake (older AVX512) systems you can enable it with SetMaxCPU("avx512base+") and get the optimized AVX512_BASE functions.
Build: add new architecture z/Architecture
