Split plug gfci replacement
Technically, the only way to accomplish what you're asking is to use a double pole 20A GFCI breaker, as there is no such thing as multi-wire branch circuit GFCI receptacle. 

Preferably, if it existed, you'd use a double pole 20A DFCI "Dual GFCI + AFCI" breaker, but until then your only option is the GFCI double pole.
