feat(Clarity2) Get burnchain_header_hash by burnchain_height

[gregorycoppola]

Fixes #2663

Description

This change allows a clarity contract to get the header hash of a burnchain block using the burchain height. Currently, you can get the header hash of the burnchain only using the Stacks height.

Testing

Tests have been added in the following files:

M	src/chainstate/stacks/boot/contract_tests.rs
M	src/vm/analysis/arithmetic_checker/tests.rs
M	src/vm/analysis/type_checker/tests/mod.rs
M	src/vm/tests/contracts.rs
M	src/vm/tests/costs.rs

A TODO was added to modify the following integration test. We avoid doing this now because it will require having a way to configure the Stacks Epoch for the Mocknet miner.

M	testnet/stacks-node/src/tests/integrations.rs

[gregorycoppola]

added some pointers to implementations
