Add getGLMatrix method to MatrixState

Add getGLMatrix method to MatrixState

Removes redundant code by consolidating it into a single method. No
change in functionality, this is strictly a refactoring.

looks good

https://codereview.chromium.org/23767005/diff/4001/src/gpu/gl/GrGpuGL_program...
File src/gpu/gl/GrGpuGL_program.cpp (right):

https://codereview.chromium.org/23767005/diff/4001/src/gpu/gl/GrGpuGL_program...
src/gpu/gl/GrGpuGL_program.cpp:223: GL_CALL(LoadMatrixf(projectionMatrix));
BTW, good opportunity to simply use DSA GL_CALL version of:

glMatrixLoadfEXT(GL_PROJECTION, projectionMatrix);

We are considering having a glMatrixLoad3x3fEXT entry point that would make
sense here.
