Add helper macros for dependencies based on USE_PSA

Browse source 
For now in an internal header as it's the safest option and that way we
can change whenever we want.

Later on if we think the macros can be useful to applications as well then we
can move them to a public location.

/**
* Internal macros for parts of the code governed by MBEDTLS_USE_PSA_CRYPTO.
* These macros allow checking if an algorithm is available, either via the
* legacy API or the PSA Crypto API, depending on MBEDTLS_USE_PSA_CRYPTO.
* When possible, they're named after the corresponding PSA_WANT_ macro.
