Add screen orientation support for Linux DRM (#20154)

* On Frame-Buffer-Orientation: Add screen orientation support for Linux frame buffer and DRM applications.

This commit introduces support for screen orientation across various components by adding a new `Orientation` property of type `SurfaceOrientation` in `DrmOutputOptions` and `FbDevOutputOptions`. The `IScreenInfoProvider` interface is updated to inherit from `ISurfaceOrientation`, ensuring consistent orientation management.

Key changes include:
- Enhanced `FramebufferToplevelImpl` to handle orientation in size calculations.
- Updated `LibInputBackend` for device input coordinate rotation based on screen orientation.
- Implemented `ISurfaceOrientation` in `DrmOutput` and `FbdevOutput` classes.
- Modified `DrawingContextImpl` to support canvas rotation based on orientation.
- Improved `FramebufferRenderTarget` and `PixelFormatConversionShim` to respect framebuffer orientation during surface creation and pixel format conversions.
- Streamlined rendering methods to ensure drawing operations align with the current surface orientation.
- Removed redundant code related to framebuffer handling.

* Fix review comments, add ability to test

* Some formatting

* Should be working now

* Remove fbdev changes

Theres really no point to do this in fbdev.

* Better method of rotating and transforming the canvas

* Remove breaking changes

* Switch to using a 2nd frame buffer in the rotation case

* Fix review comments

* Incorrect variable

* Fix sample
