Move TLS auxiliary test scripts to the framework

[mpg]

The following files are used on the CI, shared between branches on Mbed TLS (at the time of writing identical between branches) and should be moved to the framework:

• generate_ssl_debug_helpers.py - used in CMake, Make, tests/scripts/check-generated-files.sh and scripts/make_generated_files.bat
• generate_tls13_compat_tests.py - used in CMake, Make, tests/scripts/check-generated-files.sh and scripts/make_generated_files.bat
• translate_ciphers.py - used in compat.sh andtests/scripts/components-basic-checks.sh.

For each file moved to the framework, adapt the path in all files that use it.

Note: these files are only used by mbedtls and won't be used by tf-psa-crypto, so there's no need to adapt to that repo, or worry about path differences.
