samples: bluetooth: iso_time_sync: Update configuration

Since the dependencies of `BT_ISO_CENTRAL/PERIPHERAL` options have
changed and they no longer select `BT_CENTRAL/PERIPHERAL` options
but rather depend on them, the latter must be explicitly enabled.

Also enable the nrfx_gppi helper explicitly as the sample uses it
(see controller_time_*.c). For nRF54H it will not be enabled by
the UART driver like it happens for nRF52 and nRF53.
