bug(mat-label): mat-label overlap control and does not show ellipsis

### Is this a regression?

- [X] Yes, this behavior used to work in the previous version

### The previous version in which this bug was not present was

I'm not 100% sure, but it worked before

### Description

The `mat-label` does not wrap the text with ellipsis anymore in the `mat-datepicker`. Instead the text goes over the icon/control itself.

```

To long to show all text

```

### Reproduction

Steps to reproduce:
1. Simple add create a mat-datepicker with a mat-label with new version 15.x

[Stackblitz](https://stackblitz.com/edit/angular-cv9udr-pxxmf6?file=src/app/datepicker-overview-example.ts) is available

### Expected Behavior

Before the text was trimmed with ellipsis like this:


### Actual Behavior

Now is go outside the control/over the icon:


### Environment

- Angular: 15.0.4
- CDK/Material: 15.0.3
- Browser(s): (Chrome, Edge, Firefox)
- Operating System: MacOS

Start with the linked StackBlitz reproduction and compare the Angular 15 mat-datepicker and mat-form-field label behavior with the previous version. Trace how the mat-label is rendered beside the datepicker toggle, then verify that a long label is ellipsized without overlapping the control and add regression coverage for the reproduced case.
