gsm23003: add osmo_mcc_from_str()

I found myself often using osmo_mnc_from_str() to also decode an MCC and be
strict about it, but each time I felt the need to comment like "using
osmo_mnc_from_str() also for MCC". Rather formalize this properly.

Use a static inline function, no need to add more symbols to libosmo-gsm.
