arm-bsp/docs: corstone1000: switch Ethos-U85 test flow to test_teflon

Browse Source 
Update the Corstone-1000 user guide to reflect the current Ethos-U85
test and workaround flow.

As the Corstone-1000 software stack moves to the in-tree ethosu
driver, switch the Ethos-U85 test instructions from delegate_runner to
Mesa's test_teflon application. Also update the guide to use the
renamed ethos-u85-test kas fragment and to apply the Mesa patch needed
to package test_teflon into the image.

Also replace the disable_module_autoloading kas fragment in the A320
workaround instructions with the disable-ethosu patch, to align with
the workaround flow used in systemready-patch.
