be0e42cb8f New helpers for SkYUVAInfo when used with pixmaps.
SkYUVAPixmapInfo is a SkYUVAInfo with per-plane color types and row
bytes. It describes a set of pixmaps that make up a planar image.
Consolidates validity checks of the SkYUVAInfo with the color types
and row bytes. It can provide SkImageInfos for each plane and also
assist with configuring planes to share a common allocation.

SkYUVAPixmaps is a collection of SkPixmaps that are valid for a
SkYUVAInfo. It can either wrap existing SkPixmaps or allocate and
own the memory. It consolidates validity checking of SkPixmaps with
the SkYUVAInfo. Replaces sk_gpu_test::YUVAPixmaps.

Minor tweaks to SkYUVAInfo naming, parameter order consistency, adds a
hasAlpha() method.

87d42e5d12 A new way to specify YUVA planar data from SkCodec to SkImage_Lazy
Tunnels through SkImageGenerator as well.

The new SkCodec interface doesn't assume three 8 bit planes.

New SkYUVASpec more clearly defines chroma subsampling and siting of
the planes.

The intent is to use this for other YUVA APIs as well, in particular
SkImage factories in the future.

In this change we convert to the SkYUVASpec to SkYUVASizeInfo
and SkYUVAIndex[4] representation. But the intent is to use
the SkYUVASpec representation throughout the pipeline once
legacy APIs are removed.

orientation GM is replicated to test a variety of chroma
subsampling configs.
