MPS' tracing module uses four macros:
1) TRACE( type, fmt, ... )
This acts like `printf( fmt, ... )` but also allows
the specification of a type of trace output (comment,
warning, error, ...)
2) TRACE_INIT
This acts like TRACE() but increases the level of
indentation. It will be used at the beginning of
function calls.
3) RETURN( val )
Equivalent to `return( val )` plus a decrement in the
level of indentation. This should be used at the end of
functions that have been started with TRACE_INIT.
4) TRACE_END
This combines a trace output with a decrement of the
level of indentation. It's necessary prior to leaving
functions which have been started with TRACE_INIT
but which don't have a return value.
This commit defines those macros as no-op dummies in
`library/mps/trace.h` for now.

This commit adds an MPS-specific compile-time option
`MBEDTLS_MPS_TRACE` to the internal MPS header `mps/common.h`.
So far -- this may need revisiting -- MPS comes with its own
internal tracing module which allows to track the operation of
MPS' various layers for the purpose of understanding of it workings
as well as for debugging.
The reasons for the introduction of a module separate from SSL debug
are the following:
1) The SSL debug module requires an SSL context to function because
debug callbacks are part of the runtime configuration of the SSL
module.
The MPS tracing module, in contrast, is not supposed to be used
in production environments, and there is no need for a runtime
configuration. Instead, a compile-time defined tracing callback
is used.
2) In the interest of modularity, MPS' tracing module shouldn't
require having an SSL context around.
3) Purely visually, MPS' tracing module adds support for indentation
according to call-depth and coloring according to which module is
being used, which makes it very useful for what's going on; however,
those features aren't available in the SSL debug module (and they
shouldn't be).

This commit introduces the internal MPS header `mps/common.h`
which will subsequently be populated with MPS-specific compile-time

Symmetric key management is not intended to be
delegated to drivers. Thus, key management code
for a given symmetric key type should be included
in the library whether or not the support for

symmetric key may be delegated to drivers.

Isolate the Mbed TLS cipher driver interfaces.
Do the actual cipher operations in utility
functions that are just called by the interface
functions.
The utility functions are intended to be also called
by the cipher test driver interface functions (to be
introduced subsequently) and allow to test the case
where cipher operations are fully accelerated with no
fallback (component test_psa_crypto_config_basic of
all.sh).

As per drivers, pass to the Mbed TLS implementation of

For cipher multi-part operations, dispatch based on
the driver identifier even in the case of the
Mbed TLS software implementation (viewed as a driver).
Also use the driver identifier to check that an
cipher operation context is active or not.
This aligns the way hash and cipher multi-part
operations are dispatched.

To run succesfully the test
"PSA sign: invalid algorithm for ECC key" of
test_suite_psa_crypto when ECDSA support is not included
in the library, always return INVALID_ARGUMENT
in case of an ECC key not used for ECDSA, whether
ECDSA support is present or not.
Then apply the same logic to RSA sign RSA and RSA/ECC
verify for the sake of consistency.
