Govindraj Raja a8eadc51a3 refactor(mbedtls): avoid including MBEDTLS_CONFIG_FILE
Currently we include MBEDTLS_CONFIG_FILE directly and if a custom
config file is used it will included.

However from mbedtls-3.x onwards it discourages usage of
MBEDTLS_CONFIG_FILE include directly, so to resolve this and keep 2.28
compatibility include version.h which would include the custom config
file if present and also would expose us with mbedtls-major-version
number which could be used for selecting features and functions for
mbedtls 2.28 or 3.3
