bug(MatTable): Vertical languages rotated and sticky columns

### 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

18

### Description

When there are multiple sticky columns and a column has the `writing-mode: vertical-lr` CSS rule applied (and assuming it is not the _last_ sticky column), the table does not calculate the width of the column correctly. It uses the default `horizontal-tb` mode to calculate the width and uses that instead, causing subsequent sticky columns to overlap with non-sticky columns and creates a blank space between the column with the `vertical-lr` rule and the next sticky column.

### Reproduction

StackBlitz link: https://stackblitz.com/edit/components-issue-starter-6mfsadjh?file=src%2Fmain.ts,package.json
Steps to reproduce:
1. First two columns are sticky
2. One non-sticky column has `width: 100%` to force column compression

### Expected Behavior

The second column should have a `left` value that matches the width of the first column.

### Actual Behavior

The second column uses unrotated column width as its `left` value


### Environment

- Angular: 19
- CDK/Material: 19
- Browser(s): Chrome
- Operating System (e.g. Windows, macOS, Ubuntu): MacOS

Commencez par la reproduction StackBlitz liée et comparez les deux premières colonnes sticky lorsque la colonne sticky qui n’est pas la dernière utilise writing-mode: vertical-lr. Vérifiez la valeur de left de la deuxième colonne par rapport à la largeur rendue de la première colonne ; le travail est terminé lorsque les valeurs correspondent sans chevauchement ni espace vide dans le tableau reproduit.
