[SceneChecking] Introduce SceneCheckSpecialCharacters

[alxbilger]

Check if nodes and components have special characters that may lead to undefined behavior.

The main problem in this PR is with the RequiredPlugin component. It is design to read the plugin name in its component name, and this plugin name can contain a dot. Detecting a dot leads to spamming warnings:

For example:

[WARNING] [RequiredPlugin(Sofa.Component.AnimationLoop)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.Component.Collision.Detection.Algorithm)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.Component.Collision.Detection.Intersection)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.Component.Collision.Geometry)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.Component.Collision.Response.Contact)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.Component.Constraint.Lagrangian.Correction)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.Component.Constraint.Lagrangian.Solver)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.Component.IO.Mesh)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.Component.LinearSolver.Direct)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.Component.Mapping.Linear)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.Component.Mass)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.Component.ODESolver.Backward)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.Component.SolidMechanics.FEM.Elastic)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.Component.StateContainer)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.Component.Topology.Container.Dynamic)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.Component.Topology.Container.Grid)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.Component.Topology.Mapping)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.Component.Visual)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.GL.Component.Rendering3D)] The component has the following special characters in its name: '.'
[WARNING] [RequiredPlugin(Sofa.GUI.Component)] The component has the following special characters in its name: '.'
[WARNING] [SceneCheckSpecialCharacters] Found 20 nodes or components with special characters in their names. This can lead to undefined behavior.

The dot in the name is really a problem in the current implementation of links reading. The implementation assumes that the last dot is the indication of a Data name. For RequiredPlugin, it's not the case. A solution is to fix the links reading (for example #5995). Another case is in Python. SOFA supports to access to a component using node.component_name. However, if component_name contains a dot, it will not work. So forbidding the dot is justified. For the special cases of the component RequiredPlugin, a solution is provided in #6026.
