* Extend the platform module with a util component that contains
functionality shared by multiple Mbed TLS modules. At this stage
platform_util.h (and its associated platform_util.c) only contain
mbedtls_platform_zeroize(), which is a critical function from a security
point of view. mbedtls_platform_zeroize() needs to be regularly tested
against compilers to ensure that calls to it are not removed from the
output binary as part of redundant code elimination optimizations.
Therefore, mbedtls_platform_zeroize() is moved to the platform module to
facilitate testing and maintenance.
