getSourceBasicTypes(): ReadonlySet<string>
Returns:
{ReadonlySet }

Basic source types are high-level categories like javascript, css, webassembly, etc. We only have built-in knowledge about the javascript basic type here; other basic types may be added or changed over time by generators and do not need to be handled or detected here. Some modules, e.g. RemoteModule, may return non-basic source types like "remote" and "share-init" from getSourceTypes(), but their generated output is still JavaScript, i.e. their basic type is JS.
