Move the global variable to the PSA layer, and just set that when calling PSA
level functions.
Move the internal ecp set to before each ecp call.

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.

If MBEDTLS_PSA_CRYPTO_C is enabled, we always enable
MBEDTLS_PSA_CRYPTO_CLIENT, since the client-side functions are part of the
full PSA crypto feature set. Historically, we didn't have a good place for
configuration modification, so we did this early in the crypto.h include
tree. Since Mbed TLS 3.0, we have mbedtls/build_info.h for that.
Addresses https://github.com/Mbed-TLS/mbedtls/issues/7144 .

Before, if psa/crypto_platform.h was overridden and the override didn't
include "mbedtls/build_info.h", it was possible to end up with parts of
the headers not taking the library configuration into account, if no
mbedtls header was included before "psa/crypto.h". Make sure that
the mbedtls configuration is visible from the start, no matter what is
or is not in the platform header.

Test that MBEDTLS_PSA_CRYPTO_PLATFORM_FILE and
MBEDTLS_PSA_CRYPTO_STRUCT_FILE can be set to files in a directory that comes
after the standard directory in the include file search path.

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.

Change name and document to ensure suitability only for "tags" is explicit. Add
support for output size of zero in PSA_SUCCESS case.

The mechanism of detecting unsupported ciphersuites
for OpenSSL client doesn't work on a modern OpenSSL.
At least, it fails on Travis CI which is installed
with OpenSSL 1.1.1f. So we need to skip ECDH cipher-
suites for O->m.
