Add debug assertions for node and trivia ranges

[dsherret]

Been bit by node ranges being incorrect in swc too many times. swc has a test suite for this (swc-project/swc#583), but it's not great because people often just do UPDATE=1 and overwrite the expected outputs with incorrect information.

I think it would be good to add debug only assertions for this in dprint that gets inserted into the gen_node call for debugging then have the assertions in a separate file. It should also be done for comments and tokens.
