evmtool was not respecting the --genesis option (#7518)

* EVMTool should respect --genesis option

Update the code so that the genesis file option will be respected when
set. Also, default --fork options should set a rational base fee.

 ### Fixed
-- **DebugMetrics**: Fixed a `ClassCastException` occurring in `DebugMetrics` when handling nested metric structures. Previously, `Double` values within these structures were incorrectly cast to `Map` objects, leading to errors. This update allows for proper handling of both direct values and nested structures at the same level. Issue# [#7383]

+- `evmtool` was not respecting the `--genesis` setting, resulting in unexpected trace results. [#7433](https://github.com/hyperledger/besu/pull/7433)
 
 ### Tests
 - Added a comprehensive test case to reproduce the bug and verify the fix for the `ClassCastException` in `DebugMetrics`. This ensures that complex, dynamically nested metric structures can be handled without errors.
