glave: rename codegen'd files to better reflect where they are used.

* Several of the filenames started with glvtrace_* but are also used by glvreplay and glvdebug because they are related to trace packet structures, which must be shared.
* Also rename the generated files from 'xgl' to 'vk' (at least those that are related to glave. I didn't rename the once that come from the driver's scripts).
* There were a few manually written files that needed to have updated includes due to the name changes.
