trim: Update for --exact -> --auto
Track updates to "apitrace trim" which no longer drops glBindTexture calls We still aren't sure *why* apitrace trim should have to leave these calls around, but we have a trace which only passes the trim-stress-test if these calls are untrimmed. While that mystery waits to be solved, make the test here compatible with the current behavior.
Add test to ensure that unused textures are dropped from a trace. This tests functionality recently added to "apitrace trim".
