I heard that ALTMEMPHY and UniPHY will perform calibration operation before entering user mode, but does the user need to create and set the test pattern for that?

No need to.
ALTMEMPHY and UniPHY automatically go through initialization and calibration sequence when global_reset_n is negated.
In that sequence, automatically generated test patterns are used, so there is no need for the designer to create/set test patterns.
