Allowing TF-M to be enabled without PSA ITS support (NOUP as it breaks Firmware Framework rules built in
manifest-based generation of partitions)

-This commit breaks with rules in Firmware Framework for Trusted
 Firmware-M with regards to stating that ITS is a mandatory feature.
 This can be done when PSA crypto + drivers can provide support for
 persistent keys without relying on MBEDTLS_PSA_CRYPTO_STORAGE_C being
 set when building the PSA core. This is only possible when PSA crypto
 driver provides support for persistent key (e.g. using CRACEN and KMU)
-Made TFM_INTERNAL_TRUSTED_STORAGE_SERVICE a weak_dependency to
 fix build-issues when PSA ITS is not enabled (tfm_crypto.yaml)
-Added weak_dependencies as a non_ffm_attribute for the PSA crypto
 partition (tfm_manifest_list.yaml)
