This extends our previous change to ensure that compressed meshes have tangents
Now we ensure tangents are always used. This greatly simplifies our compression code at the cost of a small amount of bandwidth
Ensure `ensure_tangents` option actually creates tangent array. Even if it is just a dummy array.
Allow mesh to generate its own tangents when using compression. This allows users to compress meshes without tangents.
Warn users if they are trying to read from tangents without providing tangents.
This defers the update to a fresh restart of the editor (to ensure we aren't mid way through loading scenes anymore.
It also ensures that the popup can't be used by multiple threads at once

This cleans up a few more cases of uint32_t->uint64_t
Importantly this fixes an edge case in the axis-angle compression by
using the pre-existing Basis methods instead
Previously, it was possible to use zero or negative values, which are
invalid.
This also prevents crashing the engine by setting a shadow size of
0 or lower from a script.
This allows Godot to automatically compress meshes to save a lot of bandwidth.
In general, this requires no interaction from the user and should result in
no noticable quality loss.
This scheme is not backwards compatible, so we have provided an upgrade
mechanism, and a mesh versioning mechanism.
Existing meshes can still be used as a result, but users can get a
performance boost by reimporting assets.
This is consistent with `xatlas_unwrap`, which isn't enabled in non-editor
builds and the Android editor either. There is currently no way to
use the lightmapper in a non-editor build anyway, as it doesn't expose
any methods (and even if there was, there would be no way to perform
UV2 unwrapping in the exported project).
This reduces binary size of a stripped Linux x86_64 export template
build by ~164 KB.
This also moves the PrimitiveMesh texel size project setting
so that it's defined when the module is disabled,
and adds a property hint to it.
Introduces support for FSR2 as a new upscaler option available from the project settings. Also introduces an specific render list for surfaces that require motion and the ability to derive motion vectors from depth buffer and camera motion.
This is needed to allow 2D to fully make use of 3D effects (e.g. glow), and can be used to substantially improve quality of 2D rendering at the cost of performance
Additionally, the 2D rendering pipeline is done in linear space (we skip linear_to_srgb conversion in 3D tonemapping) so the entire Viewport can be kept linear.
This is necessary for proper HDR screen support in the future.
As more users use compute in Godot 4, the way they do is most likely incompatible when running
on separate threads and will start erroring soon as we improve the thread safety of the render thread.
To properly run code on the render thread, this function was added. Use like this:
```GDScript
func initialize_compute_code():
....
func update_compute_code(custom_data):
...
func _ready():
RenderingServer.call_on_render_thread( initialize_compute_code )
func _process():
RenderingServer.call_on_render_thread( update_compute_code.bind(with_data) )
```
* This should optimize GDScript function calling _enormously_.
* It also should simplify the GDScript VM considerably.
NOTE: GDExtension calling performance has most likely been affected until going via ptrcall is fixed.
Users can still go down to 21 when using GL Compatibility.
This makes the default behavior match the default renderer, and thus avoids
a warning in the out of the box experience.
Also mark texture compression settings as basic, since out of the box users
who want to export to Android will need to enable ETC2/ASTC manually.
