Move EL withdrawal/consolidation request processing into core/requests

- moves deposit-related helpers (deposit signature verification, batch
verification, merkle proof verification, and activation helper) from
`beacon-chain/core/blocks` into `beacon-chain/core/helpers`
- updates call sites (Altair/Electra) to use helpers

Why?
- In gloas, the blocks package needs to call into gloas logic (e.g.
clearing builder pending payments/withdrawals on proposer slashing)
- gloas also introduces deposit-request processing which needs deposit
signature verification previously located in blocks.
That creates a Bazel/Go dependency cycle (blocks -> gloas -> blocks)
- the natural layering is for blocks and fork logic to depend on a lower
level util package for deposit verification, so moving deposit helpers
to core/helpers breaks the cycle
