…ction()

This commit improves consistency in the signature of the OpenVR interactor's
`AddAction()` function. The update ensures backward compatibility and aligns
the function with its counterpart in other interactors.

This change sets the stage for a subsequent commit that will update the
base class, introducing a virtual interface for adding actions.

This change is backward compatible and intended to improve consistency
between the signature of the function in both interactors.

And is done anticipating a subsequent commit updating the base class
to add a virtual interface for adding action.

Merge-request: vtk/vtk!10785
(cherry picked from commit 64c0ef6)

This commit virtualizes the `AddAction()` functions in the VR
interactor. The addition of the `isAnalog` parameter aims to facilitate
client applications that support both OpenXR and OpenVR runtimes. Although
the `isAnalog` parameter is ignored in the context of the OpenXR interactor,
these signatures are designed to meet the requirements of the base class
interface.

…erWindow Initialization

This commit addresses warnings in the OpenXR rendering pipeline that
occurred immediately after initialization. In such cases, when the
`XrFrameState.shouldRender` property, used to set the `ShouldRenderCurrentFrame`
flag, evaluates to False, we eliminate explicit use of the `vtkWarningMacro`.
This prevents warnings like the following from being reported after
a standard pipeline initialization:

```
Warning: In vtkOpenXRRenderWindow.cxx, line 189
vtkOpenXRRenderWindow (0000028A641868D0): Not rendered
```

This resolves issue vtk/vtk#19112 (OpenXR Renderer: always warn "Not rendered"
at startup). Additionally, the associated docstring for the
`ShouldRenderCurrentFrame` instance variable has been updated for clarity.

Furthermore, the flag "ShouldRenderCurrentFrame" is proactively reset to avoid
any attempted rendering if the function `WaitAndBeginFrame()`, used in
`vtkOpenXRRenderWindow::Render`, exits prematurely.

For more details on `XrFrameState` and `XrFrameBeginInfo`, refer to the
OpenXR specification:

- https://registry.khronos.org/OpenXR/specs/1.0/man/html/XrFrameBeginInfo.html
