Percentage is not a useful number when looking at code size changes.
Since it depends on the base of the code size. It might give
misleading information by simply looking at the numbers.

The Ubuntu 16.04 and 22.04 docker images have been updated with
earliest and latest versions of gcc and clang respectively.
This patch adds the necessary component and support functions
required for the CI to run these compilers.
For FreeBSD we invoke the function by name so a condition is added
to disable the existing test_clang_opt function for linux.

If we use option --stdout, the logging level is set as
logging.ERROR. But --verbose is able to overwrite logging level as
logging.INFO if we want to display intermediate log in the process
of code size comparison.

If we output comparison result into sys.stdout, it will print an
extra line to show information we used for code size comparison in
detail. This would be helpful if we copy & paste code size changes
in Github comment.

Previously we used dec(total) as comparison result of code size
measurement. However, it's not accurate because dec(total) is
the sum of text, data and bss. Now we show text,data instead
since those are sections we care about in code size perspective
specifically for TF-M.

Back when we introduced MBEDTLS_PSA_CRYPTO_CONFIG and it was still
experimental, it made sense that we tested it separately. Nowadays, the
feature is fully implemented, and the full config without
MBEDTLS_PSA_CRYPTO_CONFIG keeps cryptographic mechanisms that only have a
PSA implementation and aren't in the default build disabled (currently:
PBKDF2). So enable MBEDTLS_PSA_CRYPTO_CONFIG in the full config.

If we don't remove all executable files in current working
directory, we might measure code size between different architecture
and configuration. This generates a wrong code size comparison
report. This commit guarantees it runs `make clean` before build
libraries for code size comparison.

Use a switch instead of an array. The array was very hollow for some enum
types such as mbedtls_ssl_protocol_version (which formerly used small
values, but switched to using the protocol encoding as enum values in Mbed
TLS 3.2.0). Optimizing compilers know how to compile a switch into a lookup
table when the range warrants it.

The script won't generate new record file if there is an existing

The build option MBEDTLS_PSA_INJECT_ENTROPY requires some extra platform
functions, for historical reasons. To enable us to test this option, provide
a version of these functions for testing.
(These versions would actually work in production, but providing them in the
library in a way that doesn't break existing users might be slightly tricky,
so it's out of scope of this commit.)
