Removals
* Remove the MBEDTLS_REMOVE_3DES_CIPHERSUITES config.h option and makke as if
it was disabled. Remove all the 3DES ciphersuites:
MBEDTLS_TLS_DHE_PSK_WITH_3DES_EDE_CBC_SHA,
MBEDTLS_TLS_ECDH_ECDSA_WITH_3DES_EDE_CBC_SHA,
MBEDTLS_TLS_ECDHE_ECDSA_WITH_3DES_EDE_CBC_SHA,
MBEDTLS_TLS_ECDHE_PSK_WITH_3DES_EDE_CBC_SHA,
MBEDTLS_TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA,
MBEDTLS_TLS_ECDH_RSA_WITH_3DES_EDE_CBC_SHA,
MBEDTLS_TLS_PSK_WITH_3DES_EDE_CBC_SHA,
MBEDTLS_TLS_RSA_PSK_WITH_3DES_EDE_CBC_SHA,
MBEDTLS_TLS_RSA_WITH_3DES_EDE_CBC_SHA . Fixes #4367.

Remove 3DES ciphersuites
--
This change does not affect users using default settings for 3DES in `config.h`
because the 3DES ciphersuites were disabled by that.
3DES has weaknesses/limitations and there are better alternatives, and more and
more standard bodies are recommending against its use in TLS.
The migration path here is to chose from the recomended in literature alternatives.

/**
* \def MBEDTLS_REMOVE_3DES_CIPHERSUITES
*
* Remove 3DES ciphersuites by default in SSL / TLS.
* This flag removes the ciphersuites based on 3DES from the default list as
* returned by mbedtls_ssl_list_ciphersuites(). However, it is still possible
* to enable (some of) them with mbedtls_ssl_conf_ciphersuites() by including
* them explicitly.
*
* A man-in-the-browser attacker can recover authentication tokens sent through
* a TLS connection using a 3DES based cipher suite (see "On the Practical
* (In-)Security of 64-bit Block Ciphers" by Karthikeyan Bhargavan and Gaëtan
* Leurent, see https://sweet32.info/SWEET32_CCS16.pdf). If this attack falls
* in your threat model or you are unsure, then you should keep this option
* enabled to remove 3DES based cipher suites.
*
* Comment this macro to keep 3DES in the default ciphersuite list.
