tests: Add build of a PSA test driver library

Browse Source 
PR #3959 has proven that by adding a prefix
(LIBTESTDRIVER1/libtestdriver1_ in this commit) to
all MBEDTLS/PSA_* and mbedtls/psa_* symbols of a copy
of the Mbed TLS library, we can build a library that
can be linked with the Mbed TLS library.

This commit leverages this to build a PSA test driver
library based on the Mbed TLS library code.

The cryptographic features supported by the test
library are defined by:
. a minimal configuration (in the sense of config.h),
  see config_test_driver.h
. PSA_WANT_* and PSA_ACCEL_* defined macros.

The PSA_WANT_* macros have to be the same as the ones
used to build the Mbed TLS library the test driver
library is supposed to be linked to as the PSA_WANT_*
macros are used in the definition of structures and
macros that are shared by the PSA crypto core,
Mbed TLS drivers and the driver test library.

The PSA_ACCEL_* macros are intended to define the
cryptographic features that have to be removed
from the Mbed TLS library and thus supported by the
test library in test scenarios. The PSA_ACCEL_* macros
to build the test library are thus mirrored from the
ones to build the Mbed TLS library by extended the
crypto_config.h: see
crypto_config_test_driver_entension.h.
