Vulkan: Don't break render pass on read-only buffer updates When uploading to a buffer that is in use by the GPU, we either acquire a new buffer and copy the contents over, or stage the update and do a GPU copy. Ignoring all other conditions, this decision was made based on whether a small or large part of the buffer is being updated; small updates where staged. However, if the current render pass uses the buffer in read-only mode, the staged update would break it (to apply the update). In this change, this situation is detected and the acquire-and-update path is chosen even for small updates.
