We now do certain image layout transitions in the render pass instead of a barrier in EndRenderPass.
There is also an additional barrier on buffer uploads to prevent write-after-write hazard. It's a kludge on the fact that we're only tracking the most recent resource access.

This should fix an issue where draw calls could flicker if a defrag was in progress and a uniform buffer was being used.
Uniform buffer "pools" are now just a single dedicated VulkanBuffer, and the uniform buffer objects are offsets into that buffer.

Some minor stuff that's cropped up from the D3D11 work so far. This PR updates the Driver_Template with the latest API, and also fixes a crash in the Vulkan driver -- if you acquired a swapchain texture from a window that had been destroyed, there was no null check before de-referencing the WindowData.

Various changes to reduce and optimize memory usage.
- Defragmenter
- Allocate 4 16MB transfer buffers for pool
- If transfer is larger than 16MB, create temporary transfer buffer
- Fixed some issues with CopyTextureToTexture

Depth textures handle MSAA differently than color textures do, because there's no need for a resolve texture. This means the root VulkanTexture can have the sample count instead of needing an additional `msaaTex`.
This changeset also fixes a bug where the depth buffer wasn't getting cleared if there were MSAA color attachments.

This change makes Refresh behave more like FNA and other rendering APIs, where user-side textures have a sample count instead of generating MSAA RTs on the fly.
This should theoretically reduce memory consumption since subresource views no longer generate their own MSAA textures. Instead, each texture with a sample count > 1 now has a reference to an MSAA texture baked into the root texture itself, so views can just reference that.
This also simplifies VulkanRenderTarget significantly, to the point where it's just a wrapper around VkImageView. We could probably remove the abstraction entirely at this point.
Since VkRenderPass objects still require knowing the sample count, we can use the first bound texture's sample count. This means users only have to specify sample count in two places -- the graphics pipeline, and the texture. Easy enough.
I also noticed and fixed a bug with clear values with MSAA levels > 1.
