Lines are batched using the simplest fvf 'BatchVertex', however when used in an item with a custom shader material, it may attempt to translate to large_fvf without the required extra channels. To prevent this a special case in flushing is made to deal with lines.
In small batches using hardware transform, vertices would be drawn in incorrect positions due to the item transform being applied twice - once in the transform uniform, and once from the transform passed as a vertex attribute.
This PR alters the shader to ignore uniform transforms when using large FVF.
No need to waste time downloading all this when it's readily available :)
Also use the official action to setup Java 8.
Also build both architectures (armv7 and arm64v8) and generate the APK,
so we can upload it.
Remove now unused and outdated `misc/ci/android-tools-linux.sh`.

Hide the back sides of the rotation gizmo circles and add a white
outline for better visualization of the rotation "sphere".
This is a 3.2 backport of @JFons work on the master branch; all credit
goes to him.
Due to my less than eagle-like view over these functions I had assumed they were passing in a single buffer input for the changes to make buffer uploading more efficient. They aren't, which is less than ideal.
So these particular changes should be reverted. When I have some more time I'll see whether the API for these calls can be changed, because as is the multiple glSubBufferData calls could be causing stalls on some hardware.
This patch fixes two related issues. One is the race condition in issue #42107..
The other is a crash which happens when the reader is lapped near the end of the buffer.
Backport of 48e8da4 to 3.2
It can be enabled in the Project Settings
(`rendering/quality/filters/use_debanding`). It's disabled
by default as it has a small performance impact and can make
PNG screenshots much larger (due to how dithering works).
As a result, it should be enabled only when banding is noticeable enough.
Since debanding requires a HDR viewport to work, it's only supported
in the GLES3 backend.
Another bug in the octree has been discovered which can cause flickering in rare circumstances : #42895
For safety until this is fixed properly this PR reverts the default state of the octree to match the old behaviour, which doesn't appear exhibit the bug (or at least not as readily).
