The value of the first sent signature algorithm is overwritten.
This test forces only a single algorithm to be sent and then
validates that the client received such algorithm.
04 03 is the expected value for SECP256R1_SHA256.

Fix bug whereby the supported signature algorithm list sent by the
server in the certificate request would not leave enough space for the
length to be written, and thus the first element would get overwritten,
leaving two random bytes in the last entry.

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.

Looking for executables causes problems with leftover compiled test
suites from other branches when we forget to run make clean before
switching branches. Using the .data files is more robust as most of them
are tracked, so will be removed when switching branches.

For the benefit of auto-formatting tools, move from the '$placeholder'
templating syntax to a new syntax of the form:
__MBEDTLS_TEST_TEMPLATE__PLACEHOLDER
This change allows the test code template to be almost entirely valid C.
