feat: backport versioned transactions

[kewde]

This PR backport Versioned Transactions to 1.31.0 which is the only version that works on mobile right now due to the lack of BigInt and TextEncoder. Whenever a big int was required, we instead opt for a normal number which should technically be fine for now since it only impacts the slots which are currently at 227,790,149 so we don't expect it to overflow in the near future.

@kewde usually we use BN.js as a replacement for BigInt. Even if size is not a problem precision might be - not sure if that is the case here. Try 0.1 + 0.2 === 0.3 😛

How would we test this PR?

@andrejborstnik recent slot should be an integer, my assumption here is that the precision should be fine 😅

How would we test this PR?

I've also backported the tests from the original version, which all pass at the moment.
The PR will not impact any existing code, it only adds a class for parsing versioned transactions, so I would like to release a beta version and test this on mobile with the dApp browser.

@andrejborstnik https://github.com/ExodusMovement/exodus-mobile/pull/16939 works on my end, can exchange on Jupiter again!

@kewde Is this still needed?

@gutenye not for mobile, Hermes has BigInt.
