Mike Klein 4429a4f82c re-precate SkMatrix44::SkMatrix44() 
It's been driving me nuts that I can't just write `SkMatrix44 m;`,
and I often don't care whether it's initialized or not.  The default
identity constructor would be nice to use, but it's deprecated.

By tagging this constructor deprecated, we're only hurting ourselves;
our big clients disable warnings about deprecated routines and use it
freely.

A quick tally in Skia shows we mostly use the uninitialized constructor,
but sometimes the identity constructor, and there is a spread of all
three in Chromium.  So I've left the two explicit calls available.

I switched a bunch of calls in Skia to use the less verbose constructor
where it was clear that it didn't matter if the matrix was initialized.
Literally zero of the kUninitialized constructor calls looked important
for performance, so the only place I've kept is its lone unit test.

A few places read clearer with an explicit "identity" to read.

// the image. For that reason, we will benchmark decodes in five representative locations
// in the image. Additionally, this use case utilizes power of two scaling, so we will

// sampleSize is used, the size of the subset that is decoded is always
// (sampleSize*512)x(sampleSize*512).

// PNG decodes use the indicated sampling strategy regardless of the sample size, so
// these tests are sufficient to provide good coverage of our scaling options.
