RFR: 8142366: Add develop_debug and develop_trace levels to Unified Logging

[Coleen Phillimore]

Hi Rachel,

I sort of thought DevelopDebug would replace plain Develop, and 
DevelopTrace would be additional lower level.   Maybe plain Develop 
should be DevelopInfo then?

Another question - how do you specify these levels?  Is it 
-Xlog:itables=develop_debug ?

Thanks,
Coleen
