Make loops iterate over arrays using size_t index

A follow-up to commit 24b6126:
https://chromium-review.googlesource.com/c/libyuv/libyuv/+/8373923

Use the new expressions (of the size_t type) for buffer sizes in for
loops for consistency with the buffer allocation and memset calls.

[libyuv] Use Armv8.5-A architecture flags for SME and SVE2 build targets

Update BUILD.gn, CMakeLists.txt, and BUILD.bazel to specify Armv8.5-A
baseline architecture flags rather than Armv9:

• BUILD.gn: update :libyuv_sve to -march=armv8.5-a+i8mm+sve2 and
  :libyuv_sme to -march=armv8.5-a+i8mm+sme.
• CMakeLists.txt: update SME check and compile options to
  -march=armv8.5-a+i8mm+sme (SVE target already uses armv8.5-a).
• BUILD.bazel: update ENABLE_SVE_COPTS to -march=armv8.5-a+i8mm+sve2.

Using -march=armv9-a enabled baseline SVE in the compiler, causing
Clang to emit non-streaming SVE instructions (such as cntd in function
prologues prior to smstart) in SME translation units. On processors
such as Apple M4/M5 that support SME but not SVE, executing these
prologue instructions resulted in SIGILL crashes.

[libyuv] Simplify RVV configuration in BUILD.bazel and libyuv.bzl

Restructure RISC-V Vector (RVV) configuration to follow the pattern
used by NEON and SVE:

• Move RVV_COPTS immediately after SVE_COPTS.
• Define ENABLE_RVV_COPTS (-march=rv32gcv) and ENABLE_RVV64_COPTS
  (-march=rv64gcv) with SUPPORTS_RVV_COPTS (-DLIBYUV_RVV).
• Revert ALL_COPTS to PLATFORM_COPTS so RVV vector flags are not
  applied to generic sources.
• Add ALL_RVV_COPTS, RVV_DEPS, and libyuv_rvv_impl target.
• Update libyuv.bzl to add libyuv_rvv_srcs and exclude source/rvv.cc
  from libyuv_srcs.

In convert_argb_test.cc and planar_test.cc, cast stride to size_t in
align_buffer_page_end and memset calls to eliminate GCC 15
-Wstringop-overflow warnings.

Delete redundant (int) casts on sizeof in convert_argb_test.cc.

Enable RVV support in CMake and Bazel for RISC-V targets

Enable RISC-V Vector (RVV) by default when building natively on RISC-V
platforms (such as SpacemiT K1/K3) using CMake and Bazel:

• CMakeLists.txt: Detect riscv64 and riscv32, probe compiler support
  for -march=rv64gcv / -march=rv32gcv, and append architecture flags
  with auto-vectorization disabled (-fno-vectorize -fno-slp-vectorize).
  Support custom architecture flags via -DRISCV_COMPILER_FLAGS and
  provide -DUSE_RVV=OFF to disable.
• BUILD.bazel: Add RVV_COPTS for @platforms//cpu:riscv64 and
  @platforms//cpu:riscv32 with -fno-vectorize.
• docs/getting_started.md: Document native SBC builds, custom targets
  (SiFive X280, Coral 32-bit Zve32x), Bazel, and Blaze commands.

Test: cmake build on host and simulated riscv64; clang cross-compile tests

convert_from_argb: Add ARGB to NV16 and NV24

Add matrix and BT.601 wrapper APIs for converting ARGB to NV16 and
NV24. Reuse the optimized ARGB Y and UV row functions, then merge
the planar chroma rows into the interleaved destination plane.

NV16 performs horizontal 2:1 chroma subsampling on every source row.
NV24 preserves full-resolution 4:4:4 chroma. Both paths support odd
widths, negative heights, and the existing matrix constants.

Add tests that compare scalar and optimized paths at an odd width and
height through the matrix API and its BT.601 wrapper.

Do not use glob in the hdrs list of libyuv library

Some headers in the include/libyuv directory are private headers and
should not be visible to the clients of the libyuv library target. List
the public headers explicitly in the hdrs list of the libyuv library
target.

Ideally those private headers should be moved to some other directory
such as the source/ directory.

[libyuv] Keep LIBYUV_API in basic_types.h and remove legacy types and bool macros

Reduces include/libyuv/basic_types.h to only define LIBYUV_API.
Directly includes <stdint.h> and <stddef.h> where needed in public
headers.
Replaces LIBYUV_BOOL, LIBYUV_FALSE, and LIBYUV_TRUE with C++ bool,
true, and false in C++ code (MJpegDecoder, unit tests) and int (0, 1)
for C API functions.
Updates documentation and unit tests.

Test: ninja -C out/Release libyuv_unittest && ./out/Release/libyuv_unittest --gtest_filter=*

These failures could mean that the library update changed something and caused
tests to fail. You'll need to review them yourself and decide where to go from here.

In either event, I have done all I can and you will need to take it from here. If you
don't want to land my patch, you can replicate it locally for editing with
./mach vendor media/libyuv/moz.yaml

When reviewing, please note that this is external code, which needs a full and
careful inspection - not a rubberstamp.

This would be nice to have, especially for LoongArch (Loong64), since https://chromium.googlesource.com/libyuv/libyuv//+/60102bd795faf855e67a2f026797c16a25b4c42c fixes a compilation failure on it.
