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.
This may mitigate a crash seen in the wild in Rift Riff on Android, most
likely trading it for a single-frame rendering bug (which is better than
crashing on user devices).
It doesn't solve the underlying issue which seems to be a race condition
where a uniform set RID gets has been freed while still being reported as
owned by the RID_Owner.
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.

RenderingDevice::screen_get_framebuffer_format should return a value of
type RenderingDevice::FramebufferFormatID which is an alias of int64_t
but it returns Error::FAILED with a value of 1. The compiler does not
complain because both types are integers but 1 corresponds to a valid
FramebufferFormatID, meaning a certain failure condition is missed.
This commit changes it to the correct value, INVALID_ID.
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`).
Closes#108115
* Moving over to RenderingShaderContainer, missed setting shader_name
* Use forward declaration reduces compile time when modifying
rendering_shader_container.h from over 950s to about 10-15
This change introduces a new protected type, `ReflectedShaderStage` to
`RenderingShaderContainer` that derived types use to access SPIR-V and
the reflected module, `SpvReflectShaderModule` allowing implementations
to use the reflection information to compile their platform-specific
module.
* Fixes memory leak in `reflect_spirv` that would not deallocate the
`SpvReflectShaderModule` if an error occurred.
* Removes unnecessary allocation when creating `SpvReflectShaderModule`
by passing `NO_COPY` flag to `spvReflectCreateShaderModule2`
constructor function.
* Replaces `VectorView` with `Span` for consistency
* Fixes unnecessary allocations in D3D12 shader container in
`_convert_spirv_to_nir` and `_convert_spirv_to_dxil` which implicitly
converted the old `VectorView` to a `Vector`
