python-deps: bump cmake-format and autopep8

As decided at the most recent TSC meeting, bump cmake format to the
latest version. This will change/break style in many of the existing
cmake files, but pinning pyyaml to < 6 is not a long-term option.

Also bump patch version of autopep8, which should not lead to style
changes.

Bump overall sel4-deps version because the cmake-format change is
incompatible. Version 0.6.0 was not published because of the pyyaml
pinning/downgrade.
