Also adds RGBToYMatrixRow_Opt and RGBToYMatrixRow_2Step_Opt to convert_argb_test.cc to benchmark and compare the direct AVX2 conversion vs a 2-step approach.

This change implements ARGBToUV444MatrixRow_RVV, ARGBToUVMatrixRow_RVV,
and their wrappers (ARGBToUVRow_RVV, ARGBToUVJRow_RVV, etc.) using RVV
intrinsics, mirroring the NEON/AVX2 designs. It wires them into the
build and dispatch systems.
LIBYUV_RVV_HAS_TUPLE_TYPE is always true on new compilers. This macro
has been removed, assuming it is true everywhere, reducing the amount of
code in row_rvv.cc, scale_rvv.cc, and row.h.

I have successfully ported the usage of ARGBToYRow_AVX2 to dynamically detect and utilize ARGBToYRow_AVX512BW when available.
Here's a summary of the changes:
1. Source Modifications: In both source/convert.cc and source/convert_from_argb.cc, I searched for all references where ARGBToYRow_AVX2 was
being conditionally used (which operates on 32 pixels).
2. AVX512BW Detection: Immediately following those blocks, I injected a new check for kCpuHasAVX512BW. If the CPU flag is present, the logic
now utilizes ARGBToYRow_Any_AVX512BW by default, falling back to the fully aligned ARGBToYRow_AVX512BW when the width is aligned to 64
bytes.
3. Profiling: After building and compiling the tests (doyuv3x), I validated the change using perfyuv3 ARGBToNV12_Opt | cat. The test
successfully executed and the performance profile indicated that ARGBToYRow_AVX512BW successfully executed (taking up ~18% of CPU cycles,
replacing the previous AVX2 specific instruction overhead for the Y row extraction).
The HAS_ARGBTOYROW_AVX512BW macro implementation now fully supports all AVX2 conversion paths to utilize AVX512BW when the system processor
flags allow it!

Was AVX2 LibYUVConvertTest.ARGBToI444_Opt (1125 ms)
Now AVX512 LibYUVConvertTest.ARGBToI444_Opt (641 ms)
Details by Gemini:
1. Created 3 new Matrix functions:
Added ARGBToYMatrixRow_SSSE3, ARGBToYMatrixRow_AVX2, and
ARGBToYMatrixRow_AVX512BW to source/row_gcc.cc. These take the
const struct ArgbConstants* c parameter similarly to
ARGBToUV444MatrixRow_*. The x86 vector instructions dynamically
calculate the needed values using the properties of the constants
struct, including using vpmaddwd inside the AVX512 code to offset
the lack of a native vphaddw.
2. Replaced Old Functions with Wrappers:
Modified the existing implementations of ARGBToYRow_SSSE3,
ARGBToYJRow_SSSE3, ABGRToYRow_SSSE3, ABGRToYJRow_SSSE3,
RGBAToYRow_SSSE3, RGBAToYJRow_SSSE3, BGRAToYRow_SSSE3 (and their
_AVX2 equivalents) in source/row_gcc.cc to act as inline wrappers
calling the new ARGBToYMatrixRow_* functions, passing the right
matrix parameters (e.g. &kArgbI601Constants, &kArgbJPEGConstants,
&kAbgrI601Constants).
3. Added row_any.cc Handlers:
Added ANY11MC definitions to source/row_any.cc to autogenerate
ARGBToYMatrixRow_Any_SSSE3, ARGBToYMatrixRow_Any_AVX2, and
ARGBToYMatrixRow_Any_AVX512BW which safely handles non-aligned
tails.
4. Updated include/libyuv/row.h:
Updated the headers with the proper void declarations for all newly
generated Matrix and Any_ variants. Also defined
HAS_ARGBTOYROW_AVX512BW in the CPU macros.
5. Tested the Implementations:
Compiled and tested on Linux x86, which resulted in all tests passing
cleanly. Also successfully completed all Windows 32-bit build checks
ensuring 32-bit regression prevention without issues.

By maintaining the interleaved format of the data we can use a common
kernel for all input channel orderings and simply pass a different
vector of constants instead.
A similar approach is possible with only Neon by making use of
multiplies and repeated application of ADDP to combine channels, however
this is slower on older cores like Cortex-A53 so is not pursued further.
For odd problem sizes we need a slightly different implementation for
the final element, so introduce an "any" kernel to address that rather
than bloating the code for the common case.
