rsx: Improve object reuse and lifetime management

[kd-11]

• Fixes some old issues with resource management in violation handlers and the texture cache. Freeing buffers and event handles still queued for processing would cause drivers to re-issue them and cause strange results such as premature signaling and deadlocks due to use-after-free situations in the driver.
• Handle dangling queries when doing an emergency commandlist close/submit. See Regressions caused by #6112 (optimizations) #6135.
• Minor optimization by reusing temporary objects in the discard pile instead of allocating new ones. Should help lower memory utilization and may improve performance since allocations are quite expensive. The nature of identical frame-to-frame operation in games means that it is almost never required to invoke allocations unless the scene suddenly changes.

Fixes #6135

Introduces flickering in main menu and track selector in GT6.

The temp image lifetime usage is pretty awful, I'm working on it. Relegated to WIP until then.

@arabek @stride21 Retest please.

Flickering in GT6 menus now gone.
