Pull request overview

This PR tightens TypeScript declaration types for various *Expr options across DevExtreme core .d.ts files and the generated Angular/React/Vue wrappers, replacing broad Function types with explicit callable signatures to preserve more exact typings in wrapper generation.

Changes:

Replaced Function-typed *Expr members with explicit function signatures in core .d.ts files (and dx.all.d.ts).
Updated generated Angular/React/Vue wrapper prop/input typings to reflect the new callable signatures.
Adjusted related option typings for TreeView/TreeList/Gantt/FileManagement and Collection/Hierarchical widgets.
