extmod/modtls_mbedtls: Support alternate sign callbacks in Python.
This commit enables the implementation of alternative mbedTLS cryptography
functions, such as ECDSA sign and verify, in pure Python. Alternative
functions are implemented in Python callbacks, that get invoked from
wrapper functions when needed. The callback can return None to fall back
to the default mbedTLS function.
A common use case for this feature is with secure elements that have
drivers implemented in Python. Currently, only the ECDSA alternate sign
function wrapper is implemented.
Tested signing with a private EC key stored on an NXP SE05x secure element.
