cxl/decoder: add a max_available_extent attribute

Add a max_available_extent attribute to cxl_decoder. In order to aid in
its calculation, change the order of regions in the root decoder's list
to be sorted by start HPA of the region.

Additionally, emit this attribute in decoder listings, and consult it
for available space before creating a new region.
