Support for opcodes for consensus incentives

[uhudo]

Problem

Algorand 3.25.0 introduced new AVM opcodes related to consensus incentives.
For related smart contract applications, access to these opcodes is required.

Solution

Expand AcctParamsGet and Global classes with new corresponding methods.

Hi @uhudo we're just researching the status of those opcodes since they don't appear in the latest langspec yet, which is what we use to generate the op code support.
