bitbake: always emit bb.event.DepTreeGenerated
The data included in the event is useful for implementing a pre-build check that warns about unexpected components, for example because of an incorrect configuration or changed dependencies. Such a check can be done in a .bbclass that gets inherited globally. But in contrast to a UI, such a class cannot request that the event shall be emitted, and thus the event has to be emitted whether there is a consumer or not. This was done conditionally earlier out of concerns about the performance impact. But now events are handled more efficiently, so that concern no longer seems valid: in some simple testing (admittedly on a fast build workstation), the two lines (generating the data and emitting the event with it) only took about 0.05 seconds (measured with timeit). That was for a build with roughly 500 recipes (from pn-buildlist aka depgraph['pn']), triggered via the command line. That was even with a consumer of the data active and doing some work, so it should be even faster when there is no consumer.
