CONFIG_BT_USE_PSA_API was used in BT crypto/host modules to select
PSA crypto API over TinyCrypt (which was the default until now).
Since TinyCrypt is being deprecated and PSA crypto API is the new
standard library for crypto operations, CONFIG_BT_USE_PSA_API is
no more needed.

By enabling CONFIG_BT_USE_PSA_API the user can specify to use
PSA APIs instead of TinyCrypt for crypto operations in bluetooth
host module.
This commit also extends tests/bluetooth/gatt in order to
add a PSA test.
