Prerequisite for the photography epic. VK snapshots today are one swapchain capture at window size, upscaled beyond that (llviewerwindow.cpp ~5473–5550). Depth snapshots, 360 capture and simpleSnapshot are unsupported under VK (~5848).

Scope:

Render the world + UI to an offscreen target of arbitrary size (tiled if it exceeds device limits), matching LL's max (7680; BD goes to 12228).
Depth readback, for the depth layer and the Depth24 format from upstream Alchemy develop (902e75e7db).
360 capture (6 faces) and simpleSnapshot (thumbnails, outfit/profile).
Hooks: LLVulkanContext::requestCapture/readCapture (vkgfx/llvulkancontext.h).

Size: M

Done in dba061e4de: offscreen World / World+HUD snapshots at the requested size (clamped to device limit and ~80% free VRAM), depth snapshots, simpleSnapshot and 360 capture (also fixed the 360 preview/save page path). Verified in world: large world, depth and 360 all work; the resize hitch per shot is acceptable.
