Couple of fixes related to transform orientation and width/height

[mv0]

These fix some trivial issues with wl_output events. The orientation one is of particular useful to have. For the width and height without having output_info_t as a list we will be overriding the width and height for each display_handle_mode event we get.

Both these seem unused at this point but we'll make use of them in AGL in order to have an activation area being set-up irrespective of the output dimensions or its orientation.
