This changes perp market margining to no longer assume all pnl is in USD
while settlement is in USDC. Instead, a configurable settle token is used for
pnl and settlement, defaulting to USDC.
There is no difference while the USDC price is forced to $1 and the init and liab
weights are 1. But with this patch, it becomes possible to change that.
For now it is not recommended to use a token other than USDC or USDT (or
another USD targeting stable token) for perp settlement.
The patch also updates all insurance vault use to be aware that the insurance
fund is not in USD but in USDC and apply the USDC price before payouts.
To do this, the previous PerpLiqNegativePnlOrBankruptcy was replaced by
a new PerpLiqNegativePnlOrBankruptcyV2 instruction.
