Feature request: deprecate "Defense bonus when embarked" in favor of "[100]% Strength <when defending> <when [Embarked]>"

[SpacedOutChicken]

Before creating

• This is NOT a gameplay feature from Civ VI, BNW, or outside - see Roadmap
• This is NOT a gameplay feature from Vanilla Civ V or from G&K - If so, it should be a comment in Missing features from Civ V - G&K #4697

Problem Description

The "Defense bonus when embarked" unique is no longer necessary. I propose phasing in out in favor of using the other, more versatile Strength-related uniques.

Desired Solution

See title. Individual units can have the "[100]% Strength <when defending> <when [Embarked]>" unique, and nations can have the "[100]% Strength <when defending> <for [Embarked] units>" unique.

Alternative Approaches

Presumably there are even more possible solutions, but I feel that reducing the number of base uniques is a good idea.
