Pull Request Overview
Adds a CodeQL query to warn when local inline predicates lack an overlay[caller] annotation and the supporting AST classes to recognize new overlay annotations.
- Introduces
InlineOverlayCaller.qlto flag non-private inline predicates in files withoverlay[local]/overlay[local?]annotations. - Extends the AST model in
Ast.qllwith newAnnotationArgandAnnotationsubclasses foroverlay[caller],overlay[local], andoverlay[local?].

- [nitpick] The class name
CallerArgis generic. Consider renaming it toOverlayCallerArg(and similarlyLocalArgtoOverlayLocalArg,LocalQArgtoOverlayLocalQArg) for clarity and consistency.

This PR adds a QL-for-QL query to warn about possible non-inlining across the overlay frontier for possibly local non-private inline predicates. It will be used in tandem with a script to automatically add overlay annotations to files without existing overlay annotations. Once locality annotations have been added to a file, this query takes over responsibility for warning about possible non-inlining.
Due to a limitation of the tree-sitter-ql grammar with respect to annotations on file-level module declarations (i.e.,
module;), the heuristic for determining whether an inline predicate might be local is very crude: if the file contains anyoverlay[local]oroverlay[local?]annotations.For https://github.com/github/codeql-core/issues/4951.
