Fixes and QoL (#159)

* to ensure that we're not unlocking submits too early

* a final touch

* video_core: texture_cache: fix for page table corruption

* core: linker: a name for the game main thread

* libraries: gnmdriver: an option to dump application command lists

* libraries: kernel: named guest threads

* video_core: added a heuristic for determination of CB/DB surface extents

* fix for rebase leftover
