Enable drivers when testing with GCC 15

Browse Source 
The goal of testing with GCC 15 is to validate fixes for
https://github.com/Mbed-TLS/mbedtls/issues/9814 . The bug is present in
multiple places, and some of them affect third-party drivers but not our
built-in implementation. (The bug is that driver contexts might not be
zero-initialized, but some of our built-in implementations happen not to
care about this.) Thus, enable the test drivers in the test component that
uses GCC 15, to gain the extra checks performed in the driver wrappers.
