mgmt: mcumgr: replace Tinycrypt by PSA

Browse source 
As part of ongoing work to move away from TinyCrypt and towards PSA
(#43712), make fs_mgmt use either PSA (when available) or MbedTLS
(as a fallback) for SHA-256.

The use of PSA is guarded by CONFIG_MBEDTLS_PSA_CRYPTO_CLIENT
which requires a locally-built PSA core for devices without TF-M.

======
* The support for SHA-256 (when using checksum/hash functions), previously provided
by either TinyCrypt or MbedTLS, is now provided by either PSA or MbedTLS.
PSA is the recommended API going forward, however, if it is not already enabled
(:kconfig:option:`CONFIG_MBEDTLS_PSA_CRYPTO_CLIENT`) and you have tight code size
constraints, you may be able to save 1.3 KB by using MbedTLS instead.
