Title: Adding a shim for the tracing APIs that make it easier to use the WTF

APIs from compiled code.
This contains all of the exported functions with type information and
toggles them to no-op functions that can be removed by the compiler when
WTF is forced-disabled (via a @define) or not embedded on the page.
