Spiritual weapon states (emphasis mine):
When you cast the spell, you can make a melee spell attack against a creature within 5 feet of the weapon.
[...]
As a bonus action on your turn, you can move the weapon up to 20 feet and repeat the attack.
It is clear that the caster is making the attack despite the fact that the weapon may be far away from the character itself.
A melee spell attack is a melee attack, so it satisfies the requirement for Blood Frenzy if the target has missing hit points.
Yes.
If the trait were limited to weapon attacks, it would say melee weapon attacks. As it specifies only melee attacks, it applies to melee weapon attacks and melee spell attacks, such as Spiritual Weapon.
