Add tests for superform USDC on base and mainnet

[MattPereira]

Related to balancer/code-review#257

Summary

My guess is that SuperVaults delegating ERC4626 functionality to the Yearn v3 TokenizedStrategy contract, which requires profits to be gradually unlocked over time, causes the test to fail

12 tests passed, 1 failed, 0 skipped (13 total tests)

The testWithdraw fails because of revert: too much loss;

Thanks for adding the tests Matthew. Based on me looking into this it seems like:

• Always the first fuzz iteration fails
• Even with adjusting the amountToWithdraw a bit in https://github.com/balancer/balancer-v3-erc4626-tests/blob/main/test/ERC4626WrapperBase.t.sol#L186 also the first fork-test fails.

It could be helpful if we maybe write down a small paragraph of what the withdraw fork-test does on a high leven and get the partner's opinion from one of their engineers. Ultimately we want to get as many compatible boosted pools with buffers.
