Camera: Add supportsOrientationResizePreview configuration

Current orientation resize preview patch is broken some devices (xe: tf700t). This patch adds
a new configuration for device that doesn't handle properly the orientation resize preview
detection.
Also, the patch adds some styling fixed:
- Avoice call requestLayout twice
- Avoid create variables if mOrientationResize is not going to be used
