Move SkShader::fLocalMatrix into SkShader constructor.

As a first step towards removing SkShader::setLocalMatrix, which will make
SkShader thread-safe, remove calls to setLocalMatrix that happen immediately
after the shader is being created. Instead, pass the matrix into the constructor
or factory method.
