Bluetooth: Kconfig: Enable TINYCRYPT_ECC for combined builds

Browse source 
Essentially all products that support pairing or Mesh need to be able
to support ECC. This is particularly important for traditional
peripheral/central use cases where legacy pairing is considered
insecure. With split builds we don't know if the controller supports
ECC HCI commands or not, however with a combined build we know that
the current controller lacks any special ECC support, so enable
TINYCRYPT_ECC by default for such a configuration.

to enabled for a combined build with Zephyr's own controller, since it
does not have any special ECC support itself (at least not currently).
