[PATCH v5 09/10] dts: fix topology capability comparison

[Thomas Monjalon <thomas@monjalon.net>]

TopologyCapability.__gt__() was delegating to __lt__(),
which caused infinite recursion when "other" is not a TopologyCapability:
other.__lt__(self) returns NotImplemented,
Python retries with self.__gt__(other),
and the cycle repeats.

dts/framework/testbed_model/capability.py", line 579, in __gt__
        return other < self
               ^^^^^^^^^^^^
    RecursionError: maximum recursion depth exceeded

Similarly, __le__() was delegating to "not __gt__()",
which returns True for non-comparable types instead of False.

Fix both by checking is_comparable_with() first
and comparing topology_type directly, consistent with __lt__().
