Use separate CodeQL workflow files for each language

Discussion below:

> Do we need to add more languages here?

Let us get this PR merged first before we add more languages and checks.

For example if we add the Java language to the matrix we may also need to implement "paths" or only run the Java CodeQL check when certain files change. These checks can sometimes take a while to run on the CI.

Also it is probably best to separate each language that we want to check into its own CodeQL workflow file and add all the "paths". For example:

- java-codeql-analysis.yml
- python-codeql-analysis.yml
- actions-codeql-analysis.yml
- etc

Using separate CodeQL workflow files for each language in a multi-language repository allows for tailored analysis and build processes. This approach is particularly useful when languages have different build requirements or when you want to apply specific queries or configurations to individual languages.

.github/workflows/codeql-analysis.yml と pull request 11300 の議論から始めてください。現在カバーされている言語と、それぞれのチェックをトリガーすべきファイルパスを特定してください。各言語に適切なパスと言語固有の設定を持つ独自の CodeQL ワークフローファイルがあれば完了です。
