Add GYP target for sk_tool_utils.* component.

Add GYP target for sk_tool_utils.* component.

This declares a static library target in gyp/sk_tool_utils.gyp, so other
targets can depend directly on it instead of including the source file
in their source lists.

Can this also not go in tools.gyp?

No, it creates a circular dependency. tools.gyp already includes from bench.gyp

Hmm.  Let's see if we can break the tools -> bench dependency before we do any
more of this.  I'd like to get resources and crash_handler back in tools.gyp
too.
