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.

ScalePlane's same-width vertical fast path used the endpoint-oriented
FixedDiv1 step for all upsampling. That stepping is appropriate for
bilinear interpolation, but not for point sampling, where source rows
should cover equally sized destination cells.
Use the same centered FixedDiv stepping as the generic point sampler.
Allow the point path to select the final source row while passing a
zero interpolation stride so row kernels cannot form a pointer beyond
it. Add 8-bit and 16-bit point regression coverage and verify that
bilinear upsampling remains unchanged.

In ScaleARGBBilinearUp, ScalePlaneBilinearUp, ScalePlaneBilinearUp_16,
and ScaleUVBilinearUp, dy is strictly < 65536 (dy < 1.0 in 16.16 fixed
point), so yi (y >> 16) advances strictly in unit increments (0 -> 1 ->
2 -> ... -> H - 1).
Because yi transitions across each integer row in sequence:
- src is primed at row 2 and incrementally advanced by 1 row on each
integer transition while (y + 65536) < max_y.
- When y >= max_y - 65536, src increments stop, leaving src pointing to
the final row (H - 1).
- Therefore, src is always pointing to row yi + 1 before each buffer
swap, making the inner 'src = src_ptr + yi * src_stride' recomputation
and nested 'if (yi != lasty)' checks redundant.
