Fixes shear effect with `BILLBOARD_FIXED_Y` when the camera is rotated around the z-axis by rotating the mesh correctly into view space.
Also removes shearing effects that occur when rotating the mesh by excluding the model rotation and scale from the billboard matrix.

Fixes#43733: "creating SpatialMaterial in a separate thread creates invalid
shaders (temporarily)."
The bug occurred because various setters called in materials' constructors add
materials to queues that are processed on the main thread. This means that
when the materials are created in another thread, they can be processed on the
main thread before the constructor has finished.
The fix adds a flag to affected materials that prevents them from being added
to the queue until their constructors have finished initialising all the
members.
At runtime, packed scenes with nodes marked as editable instance where
saved with node type tags, which prevented the scene to be then loaded
as an instance, causing duplicated nodes in the tree.
This change ensures nodes marked as editable instances and their owned
children are properly set as instances.
That doesn't make a difference in the editor, since such nodes where
already set as instances based on their instance state, but it helps
at runtime where instance states are disabled.

This is already supported by FreeType, but it wasn't exposed.
Adding support for WOFF2 would require linking a Brotli decompression
library in Godot, so only WOFF1 is exposed here.
Add framework for supporting geometrical occluders within rooms, and add support for sphere occluders.
Includes gizmos for editing.
They also work outside the portal system.
This comment is useful to determine the origin of ShaderMaterials
converted from built-in material types (such as CanvasItemMaterial
or SpatialMaterial).
The Godot version is also included in case the shader needs to be
regenerated with a newer engine version.
They could cause a segfault when parsing values with ID "Resource"
as apparently we never set a valid `func` for it.
Fixes crash part of #42115.
(cherry picked from commit f3aaa713d9)
Implement Octahedral Compression for normal/tangent vectors
*Oct32 for uncompressed vectors
*Oct16 for compressed vectors
Reduces vertex size for each attribute by
*Uncompressed: 12 bytes, vec4<float32> -> vec2<unorm16>
*Compressed: 2 bytes, vec4<unorm8> -> vec2<unorm8>
Binormal sign is encoded in the y coordinate of the encoded tangent
Added conversion functions to go from octahedral mapping to cartesian
for normal and tangent vectors
sprite_3d and soft_body meshes write to their vertex buffer memory
directly and need to convert their normals and tangents to the new oct
format before writing
Created a new mesh flag to specify whether a mesh is using octahedral
compression or not
Updated documentation to discuss new flag/defaults
Created shader flags to specify whether octahedral or cartesian vectors
are being used
Updated importers to use octahedral representation as the default format
for importing meshes
Updated ShaderGLES2 to support 64 bit version codes as we hit the limit
of the 32-bit integer that was previously used as a bitset to store
enabled/disabled flags
This prevents setting too large values and crashing the editor.
Very low values are also no longer allowed since they are generally
not detailed enough to represent complex gradients, leading to confusion.
