Bluetooth: PPCP: Fix not being able to disable configurations

The spec allows to set to no specific value with use of 0xffff.

As this still enables entering values in the invalid range, 3200-65535
for min/max interval, this adds the necessary build checks to prevent
values within this range to be used and at same time check if min
interval is not bigger that max interval.

Fixes #15017
