[Frax] FIP - 65 - Kill D4 Saddle pool staking rewards and move it to gauge

Quorum: 7.36m CVX

Summary:

Remove D4 Saddle pool staking rewards and move it into the gauge system.

As pointed out by community members, the dynamic and constantly updating nature of rewards for gauges are far fairer than our staking rewards and in general, it seems a good practice to move staking rewards pools into gauges.

We would like to propose to start this good practice with the D4 Saddle pool, which means removing D4 Saddle pool staking rewards and adding it as a gauge. This essentially allows FXS emission to be used more fairly for the stability of FRAX as well as the extension of the market cap of that.

This is potentially an initial proposal to move all staking rewards to the gauge system.

Implementation:

1. Remove D4 Saddle pool staking rewards.
2. Add D4 Saddle gauge.
