This fixes numerous false positives coming out of the culling system.
AABB checks are now a full separating-axis check against the frustum, with the points of the frustum being compared to the planes of the box just as the points of the box were being compared to the planes of the frustum. This fixes large objects behind the camera not being culled correctly.
Some systems that used frustums that were (sometimes mistakenly?) unbounded on one or more side have been modified to be fully enclosed.
Dual paraboloid shadowmaps were ending up with infinitely large volumes of area behind the hemisphere un-culled.
This change just adds a back plane to the convex shape used for the culling volume.
This moves the instance id member from Variant to the ObjectRC so that Variant is still the same size as before the fix (and also regardless if debug or release build).
The previous logic used the 'tools' directory within the Android sdk to validate it. That directory was recently deprecated and removed from the Android sdk folder (https://developer.android.com/studio/releases/sdk-tools)

This was a regression from 93d7ec8836 (#38110).
Mono's old implementation of Microsoft.Build hardcodes HasUnsavedChanges to
always return true.
This workaround can be reverted once we switch to official Microsoft.Build.

This references Godot's winding order at the top of every
procedural geometry class, as well as referencing other classes
within a given geometry class.
A warning about ImmediateGeometry3D performance was also added.

Now calling _reduce_node_type with debugging enabled to determine
if assert line is safe. Part of doing this required the assert line
to be stored away. Now the AssertNode line is being correctly set.
Newlines are now marked safe always

This should make headless exporting work in projects using textures
in any format.
Error messages should no longer appear when running a project
that used image formats that were previously not present in the list.

When reading SCREEN_TEXTURE in a shader, this previously only worked succesfully for the first read of the screen, because state.canvas_texscreen_used was never getting reset. This PR resets state.canvas_texscreen_used at the beginning of each joined item, so that further screen reads can happen.
This commit addresses multiple issues with `Variant`s that point to an `Object`
which is later released, when it's tried to be accessed again.
Formerly, **while running on the debugger the system would check if the instance id was
still valid** to print warnings or return special values. Some cases weren't being
warned about whatsoever.
Also, a newly allocated `Object` could happen to be allocated at the same memory
address of an old one, making cases of use hard to find and having **`Variant`s pointing
to the old one magically reassigned to the new**.
This commit makes the engine realize all these situations **under debugging**
so you can detect and fix them. Running without a debugger attached will still
behave as it always did.
Also the warning messages have been extended and made clearer.
All that said, in the name of performance there's still one possible case of undefined
behavior: in multithreaded scripts there would be a race condition between a thread freeing
an `Object` and another one trying to operate on it. The latter may not realize the
`Object` has been freed soon enough. But that's a case of bad scripting that was never
supported anyway.
Joining items across z_indices can interfere with light culling for lights which only affect certain z ranges. This PR disables joining across z_indices when lights are present, except specifically for lights with both z_min set to the global minimum (-4096) and z_max set to the global maximum (4096).
In addition, the z_index is now stored on the joined_item for accurate light culling. The z_index is also displayed in frame diagnostics.
Needed for the next commit. That's the only place in all the Godot code base
where that's attempted and it's not needed because Objects are not meant to
be copied that way.
