VectorDrawable native rendering - Step 1 of MANY

Implement path parsing from string to skia path in native. The parsing
contains two main stages:
1) Parse string into a list of nodes that contains one operation (such
   as move) and a vector of floats as params for that operation.
2) Interpret the operations defined in the nodes into SkPath operations,
   and create a skia path

Also provided unit test for parsing a string path into a list of nodes,
and then to a skia path.
