37a4fcc5b4 Prevent mbedtls_psa_register_se_key with volatile keys 
mbedtls_psa_register_se_key() is not usable with volatile keys, since there
is no way to return the implementation-chosen key identifier which would be
needed to use the key. Document this limitation. Reject an attempt to create
such an unusable key. Fixes #9253.

f555a4e26f MBEDTLS_STATIC_ASSERT: make it work outside of a function 
At the top level, the macro would have had to be used without a following
semicolon (except with permissive compilers that accept spurious semicolons
outside of a function), which is confusing to humans and indenters. Fix
that.

b6e362b82e PSA sign/verify: more uniform error on an unsupported hash 
Uniformly return PSA_ERROR_NOT_SUPPORTED if given an algorithm that includes
a hash, but that hash algorithm is not supported. This will make it easier
to have a uniform treatment of unsupported hashes in automatically generated
tests.

4201533196 Invert and rename config option 
Replace MBEDTLS_PSA_COPY_CALLER_BUFFERS with inverse:
!MBEDTLS_PSA_ASSUME_EXCLUSIVE_BUFFERS. This ensures that buffer
protection is enabled by default without any change to the Mbed TLS
config file.
