This will allow decoupling `display_server.h` from a number of headers in the
codebase which only require those enums and not all the DisplayServer API.
- Vulkan implementations in `RenderingDeviceDriverVulkan`.
- Raytracing instruction list in `RenderingDeviceGraph`.
- Functions to create acceleration structures and raytracing pipelines
in `RenderingDevice`.
- Raygen, Miss, and ClosestHit shader stages support.
- GDScript bindings.
- Update classes documentation.
- Unimplemented placeholders for Metal and D3D12.
- Build acceleration structure command.
- Expose a shader preprocessor define.
- Align build scratch address.
- Create STB after creating the pipeline.
- Separate acceleration structure barriers.
- Use transforms in TLAS instances.
- AnyHit and Intersection stages.
- Optionally set acceleration structure build input buffer usage.
- Introduce instances buffer.
- Move scratch buffers to RenderingDevice.
- Rename AccelerationStructureGeometryBits.
- Use regular buffer creation and free routines for scratch buffer.
- Store trackers in acceleration structures.
- Bump Shader SPIR-V version to 1.4
- Add Position attribute location in blas_create.
- Encapsulate MoltenVK check in preprocessor macro.
- Split SUPPORTS_RAYTRACING for pipeline and query.
- Add support for vertex bindings and UMA vertex buffers in D3D12.
- Simplify 2D instance params and move more into per-batch data to save
bandwidth

This work is a heavily refactored and rewritten from TheForge's initial
code.
TheForge's original code had too many race conditions and was
fundamentally flawed as it was too easy to incur into those data races
by accident.
However they identified the proper places that needed changes, and the
idea was sound. I used their work as a blueprint to design this work.
This PR implements:
- Introduction of UMA buffers used by a few buffers
(most notably the ones filled by _fill_instance_data).
Ironically this change seems to positively affect PC more than it does
on Mobile.
Updates D3D12 Memory Allocator to get GPU_UPLOAD heap support.

Introduce a specialised `texture_get_data` for `RenderDeviceDriver`,
which can retrieve the texture data from the GPU driver for shared
textures (`TEXTURE_USAGE_CPU_READ_BIT`).

Texture::slice_trackers is now a pointer and is allocated on demand only when a shared texture is created.
This makes copying Texture significantly faster.
The function update_perf_report() is expensive and is called every
frame.
Most of it is not necessary unless the user calls get_perf_report
Affects #102173
PR #100062 introduced BUFFER_USAGE_DEVICE_ADDRESS_BIT.
However it did so by adding a boolean to uniform_buffer_create(), called
"bool p_enable_device_address".
This makes maintaining backwards compatibility harder because I am
working on another feature that would require introducing yet another
bit flag.
This would save us the need to add fallback routines when the feature I
am working on makes it to Godot 4.5.
Even if my feature doesn't make it to 4.5 either, this PR makes the
routine more future-proof.
This PR also moves STORAGE_BUFFER_USAGE_DEVICE_ADDRESS into
BUFFER_CREATION_DEVICE_ADDRESS_BIT, since it's an option available to
both storage and uniforms.
This PR also moves the boolean use_as_storage into
BUFFER_CREATION_AS_STORAGE.
