Explicitly document that when using TLS 1.3, you must initialize PSA crypto
before starting a handshake.

As tested in https://github.com/Mbed-TLS/mbedtls/issues/6790,
after introducing side-channel counter-measures to bignum,
the performance of RSA decryption in correlation to the
MBEDTLS_ECP_WINDOW_SIZE has changed.
The default value of 2 has been chosen as it provides best
or close-to-best results for tests on Cortex-M4 and Intel i7.

Integrators of Mbed TLS may override the header files
"psa/crypto_platform.h" and "psa/crypto_struct.h" by overwriting the files
or by placing alternative versions earlier in the include file search path.
These two methods are sometimes inconvenient, so allow a third method which
doesn't require overwriting files or having a precise order for the include
path: integrators can now specify alternative names for the headers.

Regarding testing, the no_md component was never very useful, as that's
not something people are likely to want to do: it was mostly useful as
executable documentation of what depends on MD. It's going to be even
less useful when more and more modules auto-enable MD_LIGHT or even
MD_C. So, recycle it to test the build with only MD_LIGHT, which is
something that might happen in practice, and is necessary to ensure that
the division is consistent.

Using proper configuration options (i.e. MBEDTLS_SHA224_C and
MBEDTLS_SHA256_C) it is now possible to build SHA224 and SHA256
independently from each other.

This is not new, it had always been the case, just not documented.
Pointed out by depends.py pkalgs (again, now that restartable is part of
full).

muladd() (restartable or not) is only available when at least one short
weirstrass curve is enabled.
Found by depends.py curves (now that restartable is part of full).
Also, document that restartable only work for short weierstrass curves
(actually unrelated, but this made me think of that).
