Fix frame-allocated path lifecycles
bug:18667472
Previously, we were allocating per-frame temporary paths within the
PlaybackStateStruct, but these are not safe as layers allocate these
transiently. Instead, move these to the OpenGLRenderer, which has
better define lifecycle.
Additionally, don't store SkPath objects directly in vector, since
they are then subject to relocation.

A better looking and faster spot shadow.
1. This improve the looking, the star shape (spike) on long action bar is gone.
Shadow is more smooth now.
2. The performance is better, too. For averaging around rect, round rect and
circle, the spot shadow itself is 3 times faster. On N7 v1, it could be less than
0.1 ms.

Re-triangulate the spot shadow.
Fix the valid umbra detection.
This looks better b/c every vertex will have one ray shooting at it, such that
we don't miss the corner.
This performs better too, due to the polygon intersection is removed and less ray
intersection. 2x performance for rect and circle for spot shadow in test app.

Ambient shadow tessellation improvement.
Using the vertices, instead of ray casting for the triangulation.
This request a dynamic index buffer associated with vertex buffer,
so we update the VertexBuffer to support it.
The ambient shadow could be 3x-6x times faster for circle and rect now.

Make sure the theta is correctly represented and incoming polygon is CW for shadow.
Now the theta = 0 should be on +x axis.
And cos(theta) should correctly represent x value.
Without this fix, the poly theta (from atan2) can be wrongly rotated 90 degrees.
Also, make sure the incoming polygon is CW for the shadow system.
This fix visual artifacts in recent regression for spot shadows.

Use pre-computed index to draw the shadow.
Also draw the umbra part as triangle fans instead of zig zag fashion.

Calculate and show Ambient shadow.
Basically we compute the shadow as a strip of triangles, whose alpha value
is the strength of the shadow.
We use the normal to extend the geometry.
And we use static function and try to avoid new/malloc in the computation.
