Warn if mbedtls_config.h is included manually
Some projects using Mbed TLS have migrated their configuration
file (config.h -> mbedtls_config.h, or MBEDTLS_CONFIG_FILE) from Mbed TLS
2.x, and kept including check_config.h. This is unnecessary since Mbed TLS
3.0, and increasingly in 3.x it may report spurious errors because the
configuration adjustments have not been done yet.
