MBEDTLS_SSL_MAX_EARLY_DATA_SIZE: default value should be commented out in config

Numeric options should be commented out with their default values in the config
file, and a separate header file should set the default value if necessary.
This was done for most other options in #8161; do it here for
MBEDTLS_SSL_MAX_EARLY_DATA_SIZE.
