fix: restore removed export paths for backward compat with older test runners

[schaable]

PR #8001 removed the hardhat/internal/coverage and hardhat/internal/gas-analytics export paths, breaking users who upgrade hardhat but keep older versions of hardhat-mocha or hardhat-node-test-runner. This restores those exports as thin wrappers around shared logic extracted from the new hook handlers.

Not sure this needs a changeset, @alcuadrado, since it's going out in the same release as the original PR. Wdyt?
