[clr-interp] Convert logging in call stubs to use logging facility

[davidwrighton]

I think we should convert it to the LOG mechanism. When I wrote these logging statements, I had thought they would likely be very temporary, but I've used them 4-5 times since then, so they have some ongoing value. However, I'd like to see that work done in a separate PR. We should convert them to using LOG statements probably with a new LF enum value. Probably what should be done is add a new log facility enum in log.h, call it LF2_INTERPRETER. And convert these log statements to use the LOG2 macro, with info level LL_INFO10000 instead of wrapping them in #if LOG_COMPUTE_CALL_STUB blocks.
