- The AccountExpand instruction can now shrink accounts by reducing
the number of token/perp/serum/tcs/perp oo slots.
- A new AccountSizeMigration instruction can permissionlessly shrink
accounts that are too large and migrate them to the v3 layout.
- Rename the new "swap fee" to "deposit fee" and let it apply to all
deposits, not just for Swap-type flash loans.
- But don't apply it to withdrawals (effectively giving rebates!)

Tcs orders always store prices in a fixed "sell per buy" style, but users
can create them in either price direction. When they look at them later,
the ui needs to know what their preferred style is for this order.
- Update in_use_count to u16
- Pass banks to TCS cancel instruction
- Increase the in_use_count when a tcs is created and decrease on
trigger/cancel
(cherry picked from commit 5dd5c507f2)
To have more precision when storing user supplied prices and ensure that
the rounding that will occur will be tiny compared to the user-provided
precision.
Users can request token swaps to happen when the oracle price
is within a price band. Once the price is right, an executor can
trigger the swap. The executors are rewarded with a premium
over the oracle price.
This allows limit and stop loss orders on arbitrary spot pairs.
The PR comes with basic ts support and adjustments to the liquidator,
to execute available token conditional swaps.

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.

* add new event for taker trade so arb bots can verify their execution cost without waiting for consume events

It looks like it wasn't possible to exploit the program by
re-initializing the user-owned token accounts used in flash loan because
the later use of health_ais with the health computation would error out
if any token account was included there.
However, the check and a few others were too indirect. In this patch:
- We pass the number of loans into FlashLoanEnd explicitly (verified
from FlashLoanBegin)
- Add explicit checks for token mints, so it's no longer possible to use
token accounts for foreign mints in Begin when the loan amount is zero,
and it's clearer to see that the bookkeeping in End won't break if the
user reinited the account for a different mint.
- Also add a few other extra comments and checks.
The updated FlashLoanEnd instruction is called FlashLoanEndV2
