Implement and test mbedtls_mpi_mod_raw_random

In the basic/XXX=core test cases, use odd upper bounds, because the mod
version of random() only supports odd upper bounds (the upper bound is a
modulus and the mod modules only support odd moduli).

Bignum Mod Raw: pass endianness as a parameter
...
The external representation before included more than just endianness
(like reading in Mongtomery curve scalars or converting hashes to
numbers in a standard compliant way).
These are higher level concepts and are out of scope for Bignum and for
the modulus structure.
Passing endianness as a parameter is a step towards removing it from the
modulus structure.

bignum_mod_raw: Refactored Montgomery conversion functions

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.

Add merge slots to Bignum files
...
Legacy Bignum is excluded as it doesn't get regular extensions like new
ones.
Each slot uses comments of their respective filetype. Since .data files
don't have a syntax for comments, dummy test cases are used. (These test
cases will never be executed and no noise will be added to tests.)
