kconfig.nrf: Enable heap if BT_CRYPTO is enabled

The bt_crypto_aes_cmac function from bt_crypto library uses
psa_import_key function which requires memory for importing keys.
The memory is allocated in the heap, therefore MBEDTLS_ENABLE_HEAP
should be enabled.

This allows to build tests.bluetooth.bt_crypto.psa upstream tests.
