Always activate `__USE_MINGW_ANSI_STDIO` unless overridden on the command
line. This is necessary with older versions of MingW and/or Windows,
where snprintf does not always zero-terminate the buffer, and does
not support formats such as `"%zu"` for size_t and `"%lld"` for long long.
Simplify debug.h accordingly. The macros `MBEDTLS_PRINTF_SIZET`,
`MBEDTLS_PRINTF_SIZET_HAX` and `MBEDTLS_PRINTF_LONGLONG` are no longer
needed, but they are still used in our code base and must stay in debug.h
for backward compatibility.

In `test_suite_debug`, test `mbedtls_debug_snprintf()`, which uses
`mbedtls_vsnprintf()` like `mbedtls_debug_print_msg()`. Do this instead of
testing `mbedtls_snprintf()`, which might be subtly different (older
Windows runtimes had slightly different behavior for vsnprintf() vs
snprintf(); TF-PSA-Crypto might pick up a different function if the
platform configuration is different in TF-PSA-Crypto and Mbed TLS).

On some platforms, the system headers expose different interfaces depending
on what macros are defined, for example to provide different standards
compliance level. Create a common place where we can declare such macros,
so that our code can behave in the same way when it's in different files.
Individual .c files can still override these requirements by defining
macros before including the common header, if it's really necessary.

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.

Don't ship two slightly different wheels.
This reduces our platform adherence by using only `clock_gettime()` in the
library and not `gettimeofday()` as well.

Nowadays, the timing module just builds on a function that provides a timer
with millisecond resolution. In terms of platform requirements, this is
almost exactly equivalent to `mbedtls_ms_time()`
provides (`mbedtls_ms_time()` is arguably a little stronger because it is
supposed to last longer than a single timer object, but an application could
start a timer when it starts, so there's no real difference.) So it's a bit
silly that `timing.c` essentially reimplements this. Rely on
`mbedtls_ms_time()` instead.
This is an API break because in Mbed TLS 4.0, it was possible to enable
`MBEDTLS_TIMING_C` without `MBEDTLS_HAVE_TIME`. However, `timing.c` only
provided an implementation for Windows and Unix-like platforms, and on those
platforms, it is very likely that the default implementation of
`MBEDTLS_HAVE_TIME` would also work. (The main exception would be a platform
that has the traditional Unix function `gettimeofday()`, but not the 1990s
novelty `clock_gettime()`.) So make this an official requirement, as a
belated change that really should have gone into 4.0 if we'd taken the time
to dig into it.

In the TLS-Exporter for TLS 1.3 we mistakenly call PSA_HASH_LENGTH() on
an mbedtls_md_type_t when it should be called on a psa_algorithm_t.
Fortunately, these two types have almost the same values, since we have
previously aligned them to make conversion more efficient. As a result,
PSA_HASH_LENGTH() produces exactly the same value when called on an
mbedtls_md_type_t as with the equivalent psa_algorithm_t.
Thanks to this happy coincidence, fix a largely cosmetic issue (rather
than a major functional bug).

a variable declarator;
- last item's group name is NULL, not an empty string
- change then name of the macro from MBEDTLS_TLS_ID_GROUP_NAME_TABLE to
MBEDTLS_SSL_IANA_TLS_GROUPS_INFO

Keep MBEDTLS_PK_WRITE_C as guard only for "debug_print_pk" but let
"mbedtls_debug_print_crt" to work also when MBEDTLS_PK_WRITE_C is disabled.
In this case the only public key won't be printed, but the rest of the
certificate will be.
This commit also updates test coverage by duplicating test cases: now there
will be one case for when MBEDTLS_PK_WRITE_C is enabled and another one
for !MBEDTLS_PK_WRITE_C.

In tf-psa-crypto "mbedtls_pk_write_pubkey_psa()" is only available when
MBEDTLS_PK_WRITE_C is defined. Therefore we need to add this guard also
in mbedtls to "debug_print_pk" (and indirectly to
"mbedtls_debug_print_crt") and the corresponding tests using it.

Move single line printing to a separate function named
mbedtls_debug_print_buf_one_line(). This accepts one extra parameter
'add_text' to tell if the final text chars are to be printed at the end
of the line or not.
Add also mbedtls_debug_print_buf_ext() as a generalized version of
mbedtls_debug_print_buf() by adding the extra 'add_text' param.
debug_print_pk() will now use mbedtls_debug_print_buf_ext() in order not
to print chars while dumping the buffer.

"Move crypto-specific code from library/Makefile to a new file" accidentally
copied two lines instead of moving them. Remove the copy that's now in
`crypto-library.make`, since the variables are defined earlier in
`crypto-common.make`. The variables aren't actually used in
`crypto-common.make`, but they could be (arguably should be used to
define `TF_PSA_CRYPTO_LIBRARY_PRIVATE_INCLUDE`).

Define variables that are meant to be possibly overridden on the make
command line (or in a parent makefile) at the top. In particular, define
them before including the crypto and framework makefiles, so these makefiles
can use the default values if there's no parent setting.
Also move some internal variables earlier or later, so that a subsequent
refactoring step can have things in the right order in the mbedtls
per-directory makefile:
1. Define variables consumed by the per-directory crypto makefile.
2. Include the per-directory crypto makefile.
3. Use variables defined by the per-directory crypto makefile.
