DmesPlugin update

[alexandraBara]

Summary

-Add ignore_match_rules to DmesgPlugin analysis args and RegexAnalyzer.check_all_regexes, so callers can skip regex matches by MCA bank (mce_banks can be single, list, or range), line_regex, match_regex, and optional message scope; ignored banks are also excluded from mce_threshold counting.

Test plan

• pytest test/unit
• pytest test/functional (if applicable)
• pre-commit run --all-files

Checklist

• Added/updated tests (or explained why not)
• Updated docs/README if behavior changed
• No secrets or credentials committed
