Fix: Manipulator visible if root or tip of locked bone is selected

When an edit-bone was locked, we hid the transform manipulator for it.
But only if the bone itself was selected, not when the root or tip were
selected, even though they are locked then too. So this makes sure the
manipulator is shown in neither case.

CMake: Allow to use pre-compiled CentOS libraries

The goal is to make it able to use pre-compiled CentOS libraries on a
more modern system. Main issue was that it's possible that the compiler
on a newer version is defaulting to different C++11 ABI.

This change makes it so that if there is NO native libraries in the
lib folder and there IS pre-compiled CentOS folder, it will be used and
compiler will be forced to old ABI.

UI: Only hide locked transform manipulator axes for matching spaces

The manipulator would hide axes that were locked, even if the lock was
applied to a different space. That would lead to confusing behavior of
the manipulator. E.g.:
* Add armature
* Enter Pose Mode and select the bone
* Lock X and Y location in the Sidebar
* Enable the Move tool
* Only the Y axis is visible, but doesn't do anything on dragging
The manipulator would only show the Y axes, even though the lock is
applied to the bone's local Y axis, which matches the manipulators Z
axis.

Annotations: Use flag to determine if the layer is a Ruler

Proposed fix for T70141.

Before, the ruler was using the name of the layer as key, but this is very weak because if the layer name changes, the layer gets an annotation layer.

Now, the layer is marked using a flag and now it's possible to rename it.

Fix T70644 EEVEE: Bump issue with geometry node normal coordinate

Was caused by non-normalized coordinates (normals). Note this is not 100%
correct as the dFdx functions can be the same for packs of 4 pixels and the
derivated value can only be correct for one pixels.

This is because smoothed normals are a non-linear function (because of the
normalization).

The correct fix would be to do the dFdx offset BEFORE any normalization.

Fix T70614 EEVEE: Bump with texture connected to other branches don't work

Was caused by the bump node not being evaluated because the other branch

To fix this, we use fromnode instead of tonode.

Also we fix a potential issue with recursiveness because
ntree_shader_copy_branch() also use nodeChainIterBackwards() which would
reset the iter_flag in the middle of the parent iteration. Use iter_flag
as a bitflag for each iteration to fix this.
