Viewport Compositor: Platform support message.

In the previous situation the message was shown for Apple devices.
But this is not correct and confusing.

- Apple with Metal backend are supported, OpenGL on Apple isn't
- Legacy devices on Windows or Linux are also not supported.

This change will check that the capabilities of the GPU match the
requirements to use Viewport compositor. Based on those capabilities
a message is shown and the panel is activated.
