library: alignment.h: add internal symbol to disable optimizations on x86

Browse Source 
MBEDTLS_ALIGNMENT_DISABLE_EFFICENT_UNALIGNED_ACCESS is used to forcedly
prevent MBEDTLS_EFFICIENT_UNALIGNED_ACCESS from being set. This prevents
optimizations from being used on x86 which is useful for testing
purposes.
