Update framework to use M34 version of Skia.

These changes are needed due to changes in the Skia API.

Depends on https://googleplex-android-review.git.corp.google.com/#/c/439626/1
(Ic3cf846b74d6f10ec30c477b50fd774cc30ad52c)

BitmapFactory.cpp:
Use SkColorType instead of SkBitmap::Config, where possible.
Call SkBitmap::info() instead of deprecated SkBitmap::asImageInfo().
Remove calls to deprecated SkBitmap::getSize64().

Canvas.cpp:
ColorFilter.cpp:
Matrix.cpp
Remove the deprecated SK_SCALAR_IS_FIXED path. Leave in an else case for
SK_SCALAR_IS_FLOAT, to allow for eventual SK_SCALAR_IS_DOUBLE path.

Graphics.cpp:
Like in BitmapFactory.cpp, use new methods for determining the size of
pixels.

Paint.cpp:
Use more precise SkScalar_ToInt versions of macros.

TextLayoutCache.cpp:
Fix bug in macro definition for HB_SurrogateToUcs4.
Use the new name for SkCreateTypefaceForScriptNG.

android_view_SurfaceControl.cpp:
Replace ScreenshotPixelRef with a Skia pixel ref.

This is a merge from master-skia branch:
