bug(mat-error,mat-hint): mat-error and mat-hint display leading spaces

### 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

14.2.7

### Description

In versions pre mdc migration mat-hint and mat-error do NOT display leading spaces.
In versions post mdc migration mat-hint and mat-error do display leading spaces.

This behavior causes multi-line hints and errors to not align properly.

Of course this just a small thing an can be fixed by formatting the html differently but it is technically an undocumented breaking change. So i need to know if this is intended behavior and i have to fix it in my code or if it will be fixed in angular material.

Apparently there was already an issue for that #26430 but it was closed for not being reproducable but my StackBlitz Links show that it is still the case.

### Reproduction

Working StackBlitz link (14.2.7): https://stackblitz.com/edit/xxdwty?file=src%2Fapp%2Fform-field-appearance-example.html
Error StackBlitz link (16.2.1): https://stackblitz.com/edit/qopght?file=src%2Fexample%2Fform-field-appearance-example.html,src%2Findex.html

### Expected Behavior

Leading spaces are not displayed.

### Actual Behavior

Leading spaces are displayed.

### Environment

- Angular: 16
- CDK/Material: 16.2.1
- Browser(s): Chrome
- Operating System (e.g. Windows, macOS, Ubuntu): Windows

Start with the linked StackBlitz examples, comparing src/app/form-field-appearance-example.html from Angular Material 14.2.7 with src/example/form-field-appearance-example.html and src/index.html from 16.2.1. Confirm the leading-space behavior in mat-hint and mat-error, then verify that the expected behavior is restored without breaking multiline alignment.
