Add type annotations to opengl_mobject.py (#4398)

* feat(manim.mobject.opengl): added type annotations for `opengl_compatibility.py`

* feat(manim.mobject.opengl): typed almost all attribute definitions in `OpenGLMobject.__init__`

* feat(manim.mobject.opengl): typed more methods for `OpenGLMobject`

* fix(manim.mobject.opengl): import `override` from `typing_extensions`

* fix(manim.mobject.opengl): import `Never` from `typing_extensions`

* feat(manim.utils.config_ops): made `_Data` descriptor generic, to allow correctly typing `OpenGLMobject`

* fix(mypy.ini): don't ignore `manim.mobject.opengl.opengl_mobject`

* fix(manim.utils.config_ops): import `TypeVar` from `typing_extensions`, because the `typing` one does not have the `default` argument.

* feat(manim.mobject.opengl.opengl_mobject): Type checked more methods in `OpenGLMobject`.

* fix(manim.mobject.opengl.opengl_mobject): Fix a typo in `OpenGLMobject.restore`.

* feat(manim.mobject.opengl.opengl_mobject): Typed more methods in `OpenGLMobject`.

* feat(manim.mobject.opengl.opengl_mobject): Moved `overload`s inside an `if TYPE_CHECKING` statement.

* feat(manim.mobject.opengl.opengl_mobject): Added type annotations for `**kwargs` in a set of related methods.

* Revert "feat(manim.mobject.opengl): added type annotations for `opengl_compatibility.py`"

This reverts commit 1cd1550.

* fix(OpenGLMobject): defined `get_array_attrs` method (and typed `_original__init__` at class scope).

I followed the advice of an existing `# TODO` comment and the implementation in `Mobject`. This also resolves a mypy error in this class (missing attribute).
It's interesting because the `get_array_attrs` method is (was) only defined in three classes:
- `Mobject`
- `PMobject`
- `OpenGLPMobject`

* feat(manim.mobject.opengl.opengl_mobject): Added type annotations for the `override_animate()`.

* feat(manim.mobject.opengl.opengl_mobject): Added type annotations to `_AnimationBuilder` and some methods in `OpenGLPoint`.

* fix(manim.mobject.opengl.opengl_mobject): fix failing tests

* fix(OpenGLMobject): default implementation of `pointwise_become_partial(…)` had to return `self`!

* feat(OpenGLMobject): added `type: ignore[no-untyped-call]` for calls to `ShaderWrapper` methods (not yet annotated).

* feat(OpenGLMobject): annotated shader-related `ClassVar`s

* feat(OpenGLMobject): typed several `**kwargs` and added `type: ignore[no-any-return]`s for cases where mypy cannot understand operations on numpy arrays.

* feat(OpenGLMobject): typed more `**kwargs` and fixed `set_color` arguments

* feat(OpenGLMobject): Added more type annotations.

* feat(OpenGLMobject): Typed `OpenGLMobject.uniforms` and `OpenGLMobject.fixed_orientation_center`

* fix(OpenGLMobject): fix tests

* fix(OpenGLGroup): annotate `**kwargs`

* fix(OpenGLPoint): annotate `**kwargs`

* fix(OpenGLPoint): corrected `**kwargs` and removed two `type: ignore`s

* fix(OpenGLPoint): removed `# type: ignore[no-untyped-call]`s

* fix(ci): import `Self` from `typing_extensions` rather than `typing`.

* fix(ci): import `TypeAlias` from `typing_extensions` rather than `typing`.

* feat(OpenGLMobject): make use of PEP 728.

* fix(ci): update `typing-extensions` requirement to the first version that supports PEP 728.

* fix(OpenGLMobject): avoid variable redefinitions in the `arrange_in_grid` method.

* fix(mypy.ini): remove unused changes to `mypy` configuration.

* fix(OpenGLMobject): use different symbols for the two `updater` variables.

* Revert "fix(ci): update `typing-extensions` requirement to the first version that supports PEP 728."

This reverts commit 69b96c6.

* fix(OpenGLMobject): remove `TypedDict`s and switch to the less precise `**kwargs: Any`.

* Handle three no-any-return issues.

* Removed the slash divider in function parameters

* Removed the slash divider in function parameters

* Keep a single slash divider - to make return types match
