Bug 1510490 - Measure shader cache memory usage and remove total_gpu_bytes. r=mattwoodrow The latter causes confusion in the memory reports because it gets summed up and thus effectively doubles the reported texture memory usage. I've decided it's best to drop, and so might as well do that while we're already messing around with the memory reports and the associated boilerplate. Depends on D13439 Differential Revision: https://phabricator.services.mozilla.com/D13440
