GX2+TCL: Reimplement command buffer submission

Browse source 
- GX2 utilizes TCL(.rpl) API for command submission instead of directly writing to an internal GPU fifo
- Submission & retire timestamps are correctly implemented as incremental counters
- Command buffering behaviour matches console
- Fixes race conditions on aarch64
