CID is now enabled in the default config (as well as full), so it's
already tested in numerous all.sh components, not need to add one for
that.
We need a component for the legacy/compat option though as it's never
enabled in existing components. So, keep that one, but adjust the name
and fix a typo in a message.

We don't need to have two copies of the test with one of them depending
on legacy/compat CID: we can have just one copy, but make sure we run
ssl-opt.sh both in a build with standard CID and in a build with
legacy/compat - that's the job of all.sh (see next commit).

When legacy CID is enabled at compile time, but not used at runtime, we
would incorrectly skip the sequence number at the beginning of the AAD.
There was already two "else" branches for writing the sequence number
but none of them was taken in that particular case.
Simplify the structure of the code: with TLS 1.2 (we're already in that
branch), we always write the sequence number, unless we're using
standard CID.

Per suggestion from Manuel, I removed this redundant test.

This patch updates the `mbedtls_mpi_mod_raw_conv_xx()` methods
as follows:
* Renamed for simplicity: conv_fwd -> from_mont_rep, conv_inv -> to_mont_rep.
* Uncoupled the dependency on the legaly bignum interface.
* `mbedtls_mpi` is no longer used for temporary buffer allocation.

This patch moves `BignumModRawOperation` and `BignumModRawOperationArchSplit`
outside of the scaffolding merge slot.
It also renames `r_sqrt` property to `r2`.

This patch modifies the BignumModRawOperation class to
provide special access to key members commonly used
in tests.
It binds the module's getters to conversion functions
which enable automatic conversions such as:
* hex to int.
* zero padding hex strings.
* common Montgomery constants such as R, R^2 and R^01
are now be calculated upon access.
class `BignumModRawOperationArchSplit` is also updated to
utilise the new design.

This patch is adding a basic instantance of `BignumModRawOperation`
and creates an `BignumModRawOperationArchSplit` class, copying
over the implementation of `BignumCoreRawOperationArchSplit`.

A core MPI must have at least 1 limb. We can no longer test with 0 limbs,
and we don't need to anyway, so don't try.

This way static analyzers have a chance of knowing we don't expect the
bignum functions to support empty inputs. As things are, Coverity keeps
complaining about it.

Instead of corrupting the public key part of the message,
corrupt the proof part. A proof is conceptually similar to a signature,
and changing anything in it should make it invalid with
a high probability.
Also, instead of shifting data, perform a bitflip.
