Efl.Canvas.Vg.Object: Optimize Ector Surface Size

Summary:
The ector surface size was determined by the size of the vg object.
vg object is usually sized by the size of the container.
So, the ector surface is set unnecessarily large.
This patch sets the ector surface size to the path boundary.
And the path boundary refers to the stroke width and miterlimit.

Test Plan:
vector sample
{F3887634}
{F3887632}

[grey area is ector surface size]
{F3887633}
