Vulkan: Add single-level mutable texture flushing So far, the feature to flush mutable textures after switching to a new texture only applied to textures with at least two mip levels. In that case, the whole mip chain would be allocated for those textures. This change will add single-level texture flushing as well. However, the it should be optimized to prevent allocating the whole mip chain for only one defined level, and reduce memory usage. * Updated the code for previous texture flushing to include one-mip textures as well. * Added the condition that the mutable texture not be bound as an attachment for flushing. * Changed ImageMipLevels::FullMipChain to ::EnabledLevels in order to limit the number of allocated mips. * Removed ::FullMipChain from ImageMipLevels.
