The VKMem log line reports raw imgs -71420. LLImageRaw::sRawImageCount is decremented more often than it's incremented: some constructor or copy / move path doesn't count, or a destructor path counts twice.

It's bookkeeping only (not a leak by itself), but it makes the counter useless for spotting the real raw-image leaks we care about for RAM (see the CPU texture copies ticket). Audit every LLImageRaw constructor, assignment and move, and the Vulkan path's raw handling, so the count matches live objects. Then log it next to cpu tex.

Verified: the VKMem line now reads a steady 'raw imgs ~7094' (was -71420). The missing increment was in the const-copy constructor (0415f39fe6).
