Eliminate deprecated RPC methods

[steveluscher]

The following deprecated methods are being removed in Agave 2.0:

• confirmTransaction
• getSignatureStatus
• getSignatureConfirmation
• getTotalSupply
• getConfirmedSignaturesForAddress
• getConfirmedBlock
• getConfirmedBlocks
• getConfirmedBlocksWithLimit
• getConfirmedTransaction
• getConfirmedSignaturesForAddress2
• getRecentBlockhash
• getFees
• getFeeCalculatorForBlockhash
• getFeeRateGovernor
• getSnapshotSlot
• getStakeActivation

Clean all references and code for these from web3.js.

I've started to have a few second thoughts here.

1. Responsibly removing these methods would require a major version bump, which would take legacy web3.js to 2.0.
2. The new library that we actually intend on releasing as web3.js 2.0 already has these methods gone.

I think maybe we just cut our losses for legacy, and close #2859 by releasing the new library. Two birds, one stone.

Hi Steve,

Is there an estimate on when the new library will be released? Or, if it is already released, can you help me with a link?
