Robust script for estimating the max segment and the tranche counts

[PaulRBerg]

Context

While reviewing Shub's gas estimation script here, it dawned on me that we have been too lax about the values of MAX_SEGMENT_COUNT and MAX_TRANCHE_COUNT.

Basically, we have relied on heuristics and quick-and-dirty scripts to obtain them.

It's about time to develop a robust shell script for estimating the max segment and the tranche counts. My rationale is thus:

• We are deploying to 10+ chains, a number which will only increase over time
• Chains can change their total gas limit, which may require us to be agile and redeploy the contracts with new max counts
• There are nuances regarding the block gas limits on some chains such as Avalanche

Mechanism of Action

The script would work something like this:

• Hard-code the (known) block gas limits for our deployment chains (until Forge Std implements my feature request)
• Gas golf createWithDurations (which is always more expensive than createWithTimestamps) until the consumed gas is right below the block gas limit per chain
• Allow the user to run the script for only one chain, or for all of them
• Subtract 10 from the previously obtained value (as an additional precaution)
• Do this for LockupDynamic and LockupTranched (separately)

A related suggestion is that we may want to turn the maxCount variable into a mapping in BaseScript.
