fix(rendering): water reflection render pass compat, anisotropy feature, shadow pool race

Browse source 
Three bugs found via AMD RADV crash log:

1. Water reflection render pass used BOTTOM_OF_PIPE as srcStageMask but
   pipelines were created against the main pass (EARLY_FRAGMENT_TESTS |
   COLOR_ATTACHMENT_OUTPUT). AMD enforces strict render pass compatibility
   → SIGSEGV when scene renders into reflection texture.

2. samplerAnisotropy was never enabled during device creation despite being
   used in sampler creation — now requested via PhysicalDeviceSelector.

3. Shadow texture descriptor pool was reset each frame while prior frame's
   command buffers might still reference it. Split into per-frame-slot pools
   so each reset is fence-guarded.
