52413a93af radv: Enable NGG culling by default on GFX10.3, add nonggc debug flag. 
This commit enables NGG culling on all GFX10.3 GPUs by default.

A new debug flag environment variable RADV_DEBUG=nonggc is added to
disable this feature on GPUs where it is enabled by default.

The previous perf test flag RADV_PERFTEST=nggc will not be needed on
GFX10.3 anymore but it can still be used to enable the feature on
GPUs where it isn't on by default.

Not doing this for APUs because spilling is quite likely, due to

Also adding a flag to disable for performance debugging.

Finally adds some memset for places where we depended on the memory
being initialized to zero, which we won't get with VRAM anymore.
(I think these places should stop depending on it since it hides
 issues with executing the cmdbuffer multiple times, but this
  preserves behavior)
