all: support || operator in syzlang if condition

ex. f3 field has logic or operator in if condition:

conditional_struct {
        mask    int32
        f1      field1  (if[value[mask] & FIELD_FLAG1])
        f2      int64   (if[value[mask] & FIELD_FLAG2])
        f3      int64   (if[value[mask] == FIELD_FLAG1 || value[mask] == FIELD_FLAG2])
} [packed]
