This is required because if the user defined configuration file (not the
default one provided by mbedtls) includes files from the standard
C library then __STDC_WANT_LIB_EXT1__ won't be defined there which
cause weird build failures.

We already have `x509_internal.h` which is common to all parts of the X.509
library, and `ssl_misc.h` which is common to all parts of the TLS library.
Also create `mbedtls_common.h` which is for the Mbed TLS project as a whole.

`check_config.h` only needs to run once on the configuration. It doesn't
need to run every time an application is built. It used to be public up to
Mbed TLS 2.x because it was included from `config.h`, and users could
substitute that file completely and should still include `check_config.h`
from their file. But since Mbed TLS 3.x, including `check_config.h` is a
purely internal thing (done in `build_info.h`). So make the file itself
purely internal.
We don't need to include `check_config.h` when building every library file,
just one: `mbedtls_config.c`, that's its job.
Give the file a unique name, to avoid any clashes with TF-PSA-Crypto's
`check_config.h`.
