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.

Fix int overflow of yi * src_stride overflow in ScalePlaneVertical(),
ScalePlaneVertical_16(), and ScalePlaneVertical_16To8() by casting the
operand src_stride to ptrdiff_t.

- remove inline asm which was only for 32 bit
- add ARGBToYMatrixRow_AVX2
- add gn flag libyuv_enable_rowwin=true
Example of building with GN and Ninja:
Without the new flag:
gn gen out/Release "--args=is_debug=false"
ninja -C out/Release
With the new flag:
gn gen out/Release "--args=is_debug=false libyuv_enable_rowwin=true"
ninja -C out/Release

Declare functions as static. Declare functions in a header. Include the
header that declares the functions. Delete undeclared and unused
functions ScaleFilterRows_NEON() and ScaleRowUp2_16_NEON(). Delete
unused function ScaleY() in psnr_main.cc.
