Revert "Enable "Immersive-AR" session for OpenXR runtime" (#26092)

This reverts commit 04ee981eb70e65020bbb0ab09c0f075946697269.

Reason for revert: Breaking win-chrome
See: https://ci.chromium.org/p/chrome/builders/ci/win-chrome/15856

Original change's description:
> Enable "Immersive-AR" session for OpenXR runtime
>
> The OpenXR runtime on Windows supports both "opaque" (WMR VR devices) and "additive" (Hololens). This change simply turns on support for Immersive-AR session according to the WebXR AR-module spec. The majority of the change is to let the runtime to decide about the blend_mode and interaction_mode instead of the current guessing logic at at the renderer layer.
