Make all libgui tests print their name to logcat on begin/end

Follow up to If3811e5e553ecf97c35967128f3d59b0079d9f3a where existing
ad hoc test name logs were converted from ALOGV to ALOGD. Many tests
weren't logging their names at all, so this an attempt to centralize
and enforce that logic as much as possible.

Motivation: this makes debugging test failures significantly easier IMO.

Bug: 257123981
