Attributes: Hide internal UI attributes and disallow procedural access

This commit hides "UI attributes" described in T97452 from the UI lists
in mesh, curve, and point cloud properties, and disallow accessing them
in geometry nodes.

Internal UI attributes like selection and hiding values should use the
attribute system for simplicity and performance, but we don't want to
expose those attributes in the attribute panel, which is meant for
regular user interaction. Procedural access may be misleading or cause
problems, as described in the design task above.

These attributes are added by two upcoming patches: D14934, D14685
