Add non-breaking *Icon aliases for static icon exports

[ggdouglas]

Fixes #6258

Summary

This change introduces *Icon names for static icon component exports in @blueprintjs/icons. For example, DownloadIcon is the canonical component, and Download remains available as a deprecated alias of the same implementation (both exported from @blueprintjs/icons). The goal is to make icon imports clearer and avoid naming conflicts with common/global identifiers like Array and with other symbols (including some Blueprint components like Tag), while keeping the current API backwards compatible.

The existing unsuffixed exports still work. They are marked @deprecated on the legacy export in each generated icon module (for example export const Download in download.tsx), so TypeScript and ESLint can surface warnings when those names are used.

Changes

Representative diff from packages/icons/src/generated/index.ts

-export { AddApplication } from "./components/add-application";
-export { AddChild } from "./components/add-child";
-export { AddClip } from "./components/add-clip";
+export { AddApplicationIcon, AddApplication } from "./components/add-application";
+export { AddChildIcon, AddChild } from "./components/add-child";
+export { AddClipIcon, AddClip } from "./components/add-clip";
 …
-export { Add } from "./components/add";
+export { AddIcon, Add } from "./components/add";
 …
-export { Download } from "./components/download";
+export { DownloadIcon, Download } from "./components/download";
 …

Each line goes from exporting a single component Foo to re-exporting FooIcon (canonical) and Foo (deprecated alias) from the same ./components/foo module.

Representative diff from packages/icons/src/generated/components/download.tsx

-export const Download: React.FC<SVGIconProps> = React.forwardRef<any, SVGIconProps>((props, ref) => {
+export const DownloadIcon: React.FC<SVGIconProps> = React.forwardRef<any, SVGIconProps>((props, ref) => {
     ...
 });
-Download.displayName = `Blueprint6.Icon.Download`;
-export default Download;
+DownloadIcon.displayName = `Blueprint6.Icon.DownloadIcon`;
+
+/**
+ * @deprecated Use {@link DownloadIcon} instead.
+ */
+export const Download: typeof DownloadIcon = DownloadIcon;
+
+export default DownloadIcon;

First-party usage

Blueprint packages that import static icon components were updated to use *Icon names where needed so @typescript-eslint/no-deprecated stays clean in this repository.
