JoostK 85c7f7691e fix(common): infer correct type when `trackBy` is used in `ngFor` (#41995)
When a `trackBy` function is used that accepts a supertype of the iterated
array's type, the loop variable would undesirably be inferred as the supertype
instead of the array's item type. This commit adds an inferred type parameter
to `TrackByFunction` to allow an extra degree of freedom, enabling the
loop value to be inferred as the most narrow type.

Fixes #40125
