JoostK 51156f3f07 fix(core): allow proper type inference when `ngFor` is used with a `trackBy` function (#42692)
In #41995 the type of `TrackByFunction` was changed such that the
declaration of a `trackBy` function did not cause the item type to be
widened to the `trackBy`'s item type, which may be a supertype of the
iterated type. This has introduced situations where the template type
checker is now reporting errors for cases where a `trackBy` function is
no longer assignable to `TrackByFunction`.

This commit fixes the error by also including the item type `T` in
addition to the constrained type parameter `U`, allowing TypeScript to
infer an appropriate `T`.

Fixes #42609

public-api/

This directory contains all of the public api goldens for our npm packages we publish to NPM. These are tested on all PRs and commits as part of the our bazel tests.

To check or update the public api goldens, run one of the following commands:

yarn public-api:check
yarn public-api:update

packages-circular-deps.json

This golden file contains a list of all circular dependencies in the project. As part of the lint CI job we compare the current circular dependencies against this golden to ensure that we don't add more cycles. If cycles have been fixed, this file is also updated so that we can slowly burn down the number of cycles in the project.

To check or update the golden, run the following commands:

yarn ts-circular-deps:check
yarn ts-circular-deps:approve
