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.

Before this change, framebuffers were created based on the attachments' full dimensions, instead of the dimensions of the requested mip level. This fixes validation errors in the RenderTextureMipmaps test program.

The image type getting passed to imageCreateInfo was always VK_IMAGE_TYPE_2D, even for 3D textures. This fixes that bug, allowing Vulkan to successfully create 3D textures.

This PR adds a shader cross-compiler program (written in C#) that uses glslc and spirv-cross to compile GLSL source files to a custom, Refresh-specific shader blob format that contains shader code for various backends.
The goal is that whenever you want to compile your shaders, you just run this program (either via `refreshc` or `dotnet run`), passing in the path to the GLSL source file. You can specify which backends you want to support via flags (`--vulkan`, for instance), and it will generate a .refresh blob file for Refresh to consume.
This can also be extended via C# defines and the `partial class` system. An example is the PS5 shader implementation, whose logic is squirreled away in the NDA'd repository but can be called in sequence with the rest of the shader cross-compile logic. This way, we don't have to run two separate programs to compile our shaders to all supported platforms.
Refresh handles all the parsing of the file format in Refresh_CreateShaderModule, so individual backends do not need to concern themselves with the particulars.
