GPU-AV Settings are busted

[spencer-lunarg]

Some Settings in GPU-AV don't work in vkconfig

example:

const char *VK_LAYER_GPUAV_VALIDATE_INDIRECT_TRACE_RAYS_BUFFERS = "gpuav_indirect_trace_rays_buffers";

I tried to used VK_LAYER_GPUAV_VALIDATE_INDIRECT_TRACE_RAYS_BUFFERS=0 but wasn't working... realize the _VALIDATE_ is not part of the string

Another issue for vkconfig is gpuav_indirect_trace_rays_buffers doesn't match the indirect_trace_rays in the JSON so the setting is never noticed
