tests: bsim: Bluetooth: Enable some high reliability CAP tests

Browse source 
Enable some high reliability CAP tests by increasing ISO Tx
buffer counts in the Controller to sufficiently generate
number of complete when multiple SDUs are transmitted in
single ISO interval with use of pre-transmissions.
