GNU Make 3.81 is officially not supported (we require >= 3.82), but be nice
to XCode users who are stuck with 3.81.

Remove the experimental functions psa_generate_key_ext() and
psa_key_derivation_output_key_ext(), which require a flexible array member
and therefore break C++ code that includes Mbed TLS headers. They have been
replaced by psa_generate_key_custom() and
psa_key_derivation_output_key_custom().

In public headers, we want to avoid things that are not standard C++,
including features that GCC and Clang support as extensions, such as
flexible array members. So compile with `-pedantic`.
Non-regression for https://github.com/Mbed-TLS/mbedtls/issues/9020.

Document psa_generate_key_ext() and psa_key_derivation_output_key_ext() as
deprecated in favor of psa_generate_key_custom() and
psa_key_derivation_output_key_custom(), and no longer declared in C++ builds.
Resolves#9020.

We know it's a thin wrapper around psa_generate_key_custom, so we just need
to check that it's passing the information through, we don't need coverage
of the parameter interpretation.

Don't formally deprecate them because we don't do that in a
long-time support branch. But do point readers away from them.

Replace references to the deprecated functions `psa_generate_key_ext()` and
`psa_key_derivation_output_key_ext()` by their replacements
Implement `psa_generate_key_custom()` and
`psa_key_derivation_output_key_custom()`.

Implement `psa_generate_key_custom()` and
`psa_key_derivation_output_key_custom()`. These functions replace
`psa_generate_key_ext()` and `psa_key_derivation_output_key_ext()`.
They have the same functionality, but a slightly different interface:
the `ext` functions use a structure with a flexible array member to pass
variable-length data, while the `custom` functions use a separate parameter.
Keep the `ext` functions for backward compatibility with Mbed TLS 3.6.0.
But make them a thin wrapper around the new `custom` functions.
Duplicate the test code and data. The test cases have to be duplicated
anyway, and the test functions are individually more readable this way.
