monitor-config-manager: Support logical monitor transforms

Browse Source 
Add support for rotated monitors. This is done per logical monitor, as
every monitor assigned to a logical monitor must be transformed in the
same way. This includes being transformed on the same level; e.g. if
the backend does not support transforming any monitor of a logical
monitor natively, then all monitors will be transformed using the
offscreen intermediate framebuffer.
