There are a few added source files since the (re-)addition of GYP build
support, for better SIMD optimization support (AArch64 SME & SVE,
LoongArch LSX & LASX, RISC-V RVV). This CL covers the RISC-V RVV part in
preparation of fixing GYP builds for this architecture.
The files' arch-specific contents are all gated behind preprocessor
macro checks, so it is safe to have everything included in the build

halfwidth * halfheight does not overflow INT_MAX, matching the Y

This CL addresses two security findings related to integer overflows:
1. Input validation in ScalePlane, ScalePlane_16, and ScalePlane_12:
Added checks to reject invalid dimensions (e.g. width <= 0, height
== 0) and dimensions larger than 32768 (or smaller than -32768 for
height). This prevents FixedDiv signed integer overflows that can
lead to division by zero/overflow crashes (SIGFPE on x86) or
incorrect step calculations.
2. Stride overflow in ARGBAffineRow_C:
Casted pointer arithmetic operands to ptrdiff_t before multiplication
(y * stride and x * 4) to ensure 64-bit calculations, preventing
signed 32-bit integer overflow when calculating source pixel offsets.
Added unit tests to verify the input validation in ScalePlane functions.

Audit all occurrences of "stride *" in the libyuv source tree. Ensure
that these multiplications are performed in the ptrdiff_t type.
For functions not declared in a public header (such as static
functions), prefer to declare the stride parameters (typically named
src_stride and dst_stride) and related stride local variables as
ptrdiff_t. If this is not possible, add ptrdiff_t casts to the stride
parameters in multiplications. If intptr_t or int64_t casts were used,
change them to ptrdiff_t casts.

maintainability, and provides flexible support for various color spaces
(e.g., BT.601, JPEG full

Key Modifications:
- Function Consolidation: Refactored several high-level conversion functions into lightweight wrappers around generic Matrix variants:
- ARGBToI420 → ARGBToI420Matrix
- ARGBToI444 → ARGBToI444Matrix
- ARGBToI422 → ARGBToI422Matrix
- ARGBToNV12 → ARGBToNV12Matrix
- RAWToJ400, RGB24ToJ400 → RGBToI400Matrix
- RAWToI444, RAWToJ444 → RGBToI444Matrix
- 2-Pass Conversions: Updated RGB565ToI420, ARGB1555ToI420, and ARGB4444ToI420 to utilize 2-pass conversions via RGBToI420Matrix.
- Standardization: Refactored ARGBToNV21, ARGBToYUY2, and ARGBToUYVY to use parameterized matrix row functions (ARGBToYMatrixRow,
ARGBToUVMatrixRow).
- Legacy Cleanup: Replaced legacy calls to ARGBToYJRow with the parameterized ARGBToYMatrixRow in the ARGBSobelize helper.
- Internal Integration: Included libyuv/convert_from_argb.h in planar_functions.cc and ensured all new matrix symbols are properly
declared/exported (LIBYUV_API).
