Provide the new entropy callback

Provide the new interface for `mbedtls_platform_get_entropy()` requested
in https://github.com/Mbed-TLS/TF-PSA-Crypto/issues/307 when
`MBEDTLS_PSA_DRIVER_GET_ENTROPY` is enabled. Keep providing the old
interface when `MBEDTLS_PLATFORM_GET_ENTROPY_ALT` is enabled.

For now, the new interface is identical to the old one. Subsequent commits
will change the interface.
