bluetooth: host: Add select PSA_WANT_ALG_ECB_NO_PADDING

This is a follow-up to commit 12eee615.

Explicitly enable "PSA_WANT_ALG_ECB_NO_PADDING" to select the AES ECB
mode that it is used in CMAC operation.

This is done because CMAC uses AES-ECB, so both AES and ECB must
be explicitly enabled. Previously it worked because Mbed TLS is
not currently performing any check internally on this and it's
just enabling ECB automatically.
