bug(cdkTextareaAutosize): Autosize does not properly compute line heights when min-height or height is set via css

### Is this a regression?

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

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

_No response_

### Description

When `height` or `min-height` is set on a `textarea`, cdkTextareaAutosize does not properly calculate the line height.

I have a pull request ready to fix this issue, and will submit it shortly.

### Reproduction

StackBlitz link: https://stackblitz.com/edit/components-issue-mopjkj?file=src%2Fapp%2Fexample-component.css

### Expected Behavior

`height` and `min-height` should not affect the line height used to calculate the height based on min rows.

### Actual Behavior

`height` and `min-height` do affect the line height.

### Environment

- Angular: 16.2
- CDK/Material: 16.2
- Browser(s): Chrome (current)

Inizia con l’implementazione di cdkTextareaAutosize e riproduci il comportamento utilizzando l’esempio StackBlitz collegato, in particolare il suo src/app/example-component.css. Verifica in che modo CSS height e min-height influiscono sull’altezza della riga calcolata, quindi conferma che il dimensionamento di min-row non utilizza più questi valori.
