Aggregate --gas-stats output for multi-runner test execution

[schaable]

When multiple test runners (e.g., solidity + nodejs) are used together, --gas-stats now aggregates gas measurements across all runners and prints a single consolidated table at the end, instead of printing separate tables per runner. Follows the same approach used in the coverage plugin.

Also includes minor refactors to encapsulate internal _coverage/_gasAnalytics property access behind helper functions (getCoverageManager, setCoverageManager, getGasAnalyticsManager, setGasAnalyticsManager).

Pull request overview

Updates Hardhat’s --gas-stats behavior to produce a single consolidated gas statistics report when multiple test runners are executed in one test invocation, matching the aggregation approach already used by the coverage plugin. It also refactors internal access to _coverage and _gasAnalytics to go through helper functions instead of direct property access.

Changes:

• Aggregate gas measurements across multiple runner IDs and print one final gas stats table at the end of the overall test task.
• Add enableReport/disableReport support to gas analytics to suppress per-runner reporting during multi-runner execution.
• Introduce/get/use get*/set* helper functions for coverage and gas analytics managers across tasks and hook handlers; update tests accordingly.
