- misc fixes to utilities
- hit-testing for 3D scenes (simple version)
Had to manually inform the shader of the local-to-world matrix.
Should try making that automatic in the future.
Note: due to bug in interpreter, point-light sample can't run in raster
(yet).

3 new getters:
- localToWorld
- localToCamera
- localToDevice (same as total-matrix)
The current tracking minimizes overhead, by using a computed inverse to
produce the localToWorld/Camera. This can be change as needed in the
future (more precision, but more memory/overhead), but for now is
sufficient to try out the new APIs.

This completes pushing through the new virtual didConcat44() to our
subclasses, and introduces didScale() for future optimizations. We
don't call didScale yet, until external subclasses are also updated.

1. Feature: Clients need to override didConcat44() (new data)
2. Perf: Clients need to override didTranslate (and now didScale) so our
default impls can be empty.

The reason for the assert was breaking an assert, that if the CTM was scale/translate, that after
a preTranslate, it should still be that.
This is true... unless the new translate values are non-finite. In that case, we might turn a zero
into a NaN, (0 * non_finite --> nan), so we either have to require finite args (which we don't
at the moment) or we can't make this assert. This re-land removes that assert.
This reverts commit 268ed57d71.

Devices receive the 4x4, but by default they simply downsample it to SkMatrix.
New SkM44 matrix for the impl. It differs from SkMatrix44 in a few ways
- no tracking of "type"
- faster for concat, as it does not use doubles for intermediates
- much simpler API
There are some low-bit differences in some gms, so adding a flag for clients to
stage this change. (due to faster but lower-precision in SkM44::concat)
Performance: running canvas_matrix bench
3x3 version:
167.93 canvas_matrix_3x3 8888

105.40 canvas_matrix_2x3 8888
