Clean up resourcePath code.

1) Make the implementation of SetResourcePath/GetResourcePath of GM and SkBenchmark match with the one in Test.
2) Make gResourcePath a static pointer to const char and move it inside the classes.

BUG=None
TEST=make tests && out/Debug/tests
     make gm && out/Debug/gm
     make bench && out/Debug/bench
