Create PSA configs for ECC curves

Browse source 
For each curve defined MBEDTLS_ECP_DP_xxx_ENABLED, we have a
corrsponding PSA config define PSA_WANT_ECC_xxx.  Along with that is a
value MBEDTLS_PSA_ACCEL_ECC_xxx which can be used to allow HW
acceleration of that particular curve.

If the PSA config requests an unaccelerated curve, the corresponding
MBEDTLS_PSA_BUILTIN_ECC_xxx will also be defined.

This commit defines these for all curves currently defined, with the
defines working in either direction, depending on whether
MBEDTLS_PSA_CRYPTO_CONFIG is defined.
