/**
 * Process the filename and chunkFilename for Webpack output and MiniCssExtractPlugin.
 * This reusable function dynamically generates filenames based on the provided `pathData`,
 * a flag to determine whether to set the filename as 'index', the file extension (`ext`),
 * and a parameter to explicitly specify whether to use 'runtime' or 'name' as the dirname source.
 *
 * For non-entries entries, it returns a filename in the format '[name].[ext]'.
 * For entries, it constructs a filename with the directory name (stripping 'entries-')
 * and appends '/index' or '/[name]' (if a name is present) followed by the file extension.
 *
 * @param   pathData      - The path data object provided by Webpack.
 * @param   setAsIndex    - A flag to determine whether to set the filename as 'index'
 *                                    when processing entries. Pass `true` to use 'index' or `false`
 *                                    to use '[name]'.
 * @param   ext           - The file extension to be used for the output filename.
 * @param   dirnameSource - The pathData.chunk prop to set the directory name.
 *                                    'runtime' or 'name'. Defaults to 'name' if not provided.
 * @returns                 The generated filename.
