feat(slider): Introduce token for slider height

### Feature Description

Currently slider component has hard-coded height of 48px. In our app we need 34px height (we are replacing jquery slider control with material slider).
We cannot simply change the height of the component since internal elements (i.e. thumb) depend on the component height.
Thereby please expose the token that can be used to change height of the slider component.

### Use Case

Expose token to customize height of slider component.

Start by locating the Angular Material slider component implementation and its styling or token definitions for the hard-coded 48px height. Confirm how the thumb and other internal elements depend on that height, then verify that a token can set a 34px slider without breaking those elements.
