Make ignored dependent configuration warnings consistent between CLI options and TOML config

[mark-terry]

Description

Dependent options specified on the command line will trigger warnings, while the same options specified in a TOML file don't.

For example:
WARN | Besu | --min-gas-price has been ignored because --miner-enabled was not defined on the command line.
^ This message is displayed when the CLI options are misconfigured, but not when the same configuration is used in a TOML file.

It likely affects CLI options being verified in CommandLineUtils, which may include:

• GraphQL options
• Metrics options
• Mining options
• P2P options
• PrivacyParameters
• Privacy TLS
• RPC options
• Sync options

Acceptance Criteria

Warnings for ignored options will be displayed when using both CLI options and TOML configuration.

This line - when using toml the stringValues() method returns an empty collection but when on command line it has the expected value for the given option.
