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`

GLOBAL_GET is an expensive operation which should not be used each frame / tick.
This PR adds macros which do a cheaper revision check, and only call the expensive GLOBAL_GET when project settings have changed.

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.
