Move the declaration of the functions needed to use the test implementation of mbedtls_psa_external_get_random() to a new header file. Before, they were declared in tests/include/test/psa_crypto_helpers.h, but this header file can't be included in sample programs because it also includes headers from the library directory which is not on the include path for sample programs. This fixes the build of the sample programs when MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG and MBEDTLS_USE_PSA_CRYPTO are enabled. Move the implementation of the functions to a separate .c file as well. This isn't strictly necessary, but makes the structure of the source code easier to understand. Signed-off-by: Gilles Peskine <Gilles.Peskine@arm.com>
