Request C11 in CMake (but only for tests)
Set the C_STANDARD property on the mbedtls_test target to 11.
This requests C11 for the tests only.
If C11 is not supported the build will not fail, since
C_STANDARD_REQUIRED is not set, and memory poisoning will be disabled
by a preprocessor check on __STDC_VERSION__.
Additionally, reintroduce previous C99 enforcement on the rest of the
library.
