python: Add direct attribute paths to Read (#34833)

* python: Add direct attribute paths to Read

Supports one particular use case: read one or all endpoints,
all clusters, specific (global) attribute. See spec 8.9.2.4. This
is an allowed wildcard construct that is not currently expressable
in the API.

Test: Used on wildcard read for matter_testing_support. This is
      therefore tested on any test using that decorator - switch
      and timesync.
