psa: Move from key handle to key identifier

Browse source 
Move all the PSA crypto APIs using key handles
to use key identifiers but psa_key_open() and
psa_key_close(). This is done without modifying
any test as key handles and key identifiers are
now the same.

Update the library modules using PSA crypto APIs
to get rid of key handles.

Programs and unit tests are updated to not use
key handles in subsequent commits, not in this
one.
